America/Sitka LMT bug

(I sent this a week ago but it seems to have been lost.) I noticed this recent addition to the database: |Zone America/Sitka -14:58:47 - LMT 1867 Oct 18 | -9:01:13 - LMT 1900 Aug 20 12:00 | -8:00 - PST 1942 ... For local mean time to jump by 5.6 hours, implying that the city jumped 89 degrees to the east, would be a neat trick. Obviously the first offset is meant to be +14:58:47, and the city jumped by 24 hours or 360 degrees, crossing the IDL. -zefram

West Bank did end Daylight Saving Time this morning/midnight (2011-09-30 00:00). So West Bank and Gaza now have the same time again. Many sources, including: http://www.maannews.net/eng/ViewDetails.aspx?ID=424808 "BETHLEHEM (Ma'an) -- The Palestinian Authority announced late Thursday that clocks will be set back one hour on Friday at midnight, the official PA news agency Wafa reported."

missing extension rules
by Zefram Sept. 28, 2011

Sept. 28, 2011

I've found a problem with the tzfiles for Africa/Cairo and America/Argentina/San_Luis. They both show a last known transition in the recent past, and surprisingly lack a POSIX-TZ-format rule for extending the zone into the future. My tzfile parser treats a zone with no extension rule as being undefined for any time following the last explicit transition, so for these two zones it reckons the zone is undefined for the present. In the source files they're each currently configured to observe a set of DST rules, and the ruleset has no transitions configured for the future. So for the present and foreseeable future, the zone is on a constant offset with no DST transitions. The tzfile reflects that by showing no transitions from the present up to 2038 (where zic always fills in a complete set of expected transitions). It should be trivial to also reflect that foreseen behaviour in a POSIX-TZ string that just gives a fixed offset and no DST rule. For example, Africa/Cairo should clearly have "EET-2". I could have a go at a zic patch to fix this, if the regular zic hackers would like to work that way. For America/Argentina/San_Luis there's an extra wrinkle: the last known transition is a transition *to* DST. Its fixed-offset foreseeable behaviour therefore has a fixed is_dst=1, which is moderately silly. It's arguable that in this case it would be incorrect to give a "WARST3" extension rule, because that doesn't accurately express the DST status. Since that DST transition was in 2009, it's also a good bet that they haven't stayed continuously on DST since then, of course. -zefram

new links for time zone page on twinsun
by Steve Allen Sept. 28, 2011

Sept. 28, 2011

I suggest a few additions to the links on the twinsun time zone page http://www.twinsun.com/tz/tz-link.htm Starting last December the ITU-R has provided free online access to their recommendations. These are visible at http://www.itu.int/pub/R-REC It is a major change from the previous restrictions on ITU-R documents. This includes the time and frequency recommendations http://www.itu.int/rec/R-REC-TF/en some of which are now suppressed but which describe the history of the usage and nomenclature. In particular it has the current and two previous versions of ITU-R TF.460 which is the document that describes radio broadcast time signals and UTC. http://www.itu.int/rec/R-REC-TF.460/en The earlier versions document the connections between UTC and GMT. There are many other possibly relevant sources, but these have been deemed particularly important and they are the basis for the inputs that go to the zoneinfo database and code. -- Steve Allen <sla(a)ucolick.org> WGS-84 (GPS) UCO/Lick Observatory--ISB Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m

Information wanted #1: time zone names in Belarus, Russia, and Ukraine
by Arthur David Olson Sept. 27, 2011

Sept. 27, 2011

I'm asking for information to use in specifying time zone abbreviations for Belarus, Russia, and Ukraine. For all three I can use: 1. References to government documents that specify time zone names or abbreviations. 2. References to government documents that specify whether current time is considered to be "standard" time or "saving" time. 3. References indicating what time zone names or abbreviations are actually in use in the areas. 4. References indicating whether people in the areas consider themselves to be on "standard" or "saving" time. We do have this year's Decree #725... http://www.government.ru/gov/results/16355/print/ ...for Russia; if translate.google.com is correct, Moscow is on "Eastern Standard Time" with most other zones being "Eastern Standard Time plus n hours" and one zone being "Eastern Standard Time minus 1 hour." --ado

Or is tzdata2011k wrong? Decree #725 indicates that it abrogates Decree #23 of January 8, 1992 (among other things abrogated); is the abrogated decree available online?

RE: UTC as basis for time legislation

>> ... But other than that, if you say GMT you mean the same time as if >> you say UTC. > >Uh... you like waving red flags in front of bulls, don't you? Or maybe >walking up to a bee hive and whacking it with a short stick is your >idea of a good time. :) Ouch. My apologies to the hornets. I did some reading and I think I now understand some of the subtleties involved. Let me restate the point I should have made and hopefully not disturb another beehive. The tzdata uses an approximation of the subtle details of timekeeping. With those approximations, GMT and UTC end up being described both as having a constant 0 offset. So if country A says its legal time is an hour ahead of GMT and B says they are an hour ahead of UTC, those are technically different statements. However, to the approximation of tzdata, the outcome is the same: both country A and B would be shown in the tzdata file as having an offset of 60 minutes. Is that correct? paul

IANA and the tz database - diverging from Theory
by Tobias Conradi Sept. 26, 2011

Sept. 26, 2011

The 2011-05-19 text by E. Lear and P. Eggert at http://tools.ietf.org/html/draft-lear-iana-timezone-database-04 defines an update rule that is different to the ones in the Theory file, it reads: "3. Making Updates to the TZ Database New TZ names (e.g. locations) are only to be created when the scope of the region a name was envisioned to cover is no longer accurate." Also the Terminology section defines only three TZ specific terms, while the Theory file contains several more. Does anyone know why the rules of tz names are changed in the IANA tz text? -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com/tobias_conradi

Proposal for UTC offset coloring in maps based on 6 RGB colors
by Tobias Conradi Sept. 26, 2011

Sept. 26, 2011

This proposal is restricted to UTC offset zones, i.e. it does not propose anything for the tz zones. In the following text main zone will refer to any zone with an offset from UTC that is a multiple of 1 hour. ==Current situation== http://www.worldtimezone.com/ uses 3 colors, RGB, for main zones, as of today the map on the home page shows Kyrgysztan as +5 in the same color as neighboring China +8. repetition after 3 hours https://www.cia.gov/library/publications/the-world-factbook/maps/refmap_tim… uses 4 colors, 2 kinds of green, 1 brown, 1 yellow for the main zones. repetition after 4 hours http://www.worldtimeexplorer.com/WorldMapBig.gif uses ca. 9 colors, main zones and zone with other offsets share colors. repetition: none, e.g. orange in America is preceded by grey, while in Asia it is preceded by cyan Wikimedia offers maps with several different schemes: http://commons.wikimedia.org/wiki/File:Worldwide_Time_Zones_(including_DST)… ca. 9 colors, includes coding for DST usage Even where the following files share offsets from UTC, the colors are not necessarily shared: http://commons.wikimedia.org/wiki/File:Map_of_Russia_-_Time_Zones_(2009).svg http://commons.wikimedia.org/wiki/File:Sakha_time_zones.png http://commons.wikimedia.org/wiki/File:Map_of_Russia_-_Time_Zones_(April_20… http://commons.wikimedia.org/wiki/File:Time_zones_of_Europe.svg http://commons.wikimedia.org/wiki/File:Africa-timezones.png ==Proposal== Use 6 colors that are easily distinguished for the main zones and order them so that mixing two colors from two zones that are 2 hours apart result in the color of the zone in between. The same mixing process shall be applied for zones with an offset of 30min from a main zone. The RGB space, if each color can only be on or off, gives 2*2*2=8 possibilities which include white and black. That means there are 6 colors (Level 1 colors) that can be used. One possibility, denoting colors in hexadecimal shorthand form (f = ff, 0 = 00): UTC = f0f magenta +1 = 00f blue +2 = 0ff cyan +3 = 0f0 green +4 = ff0 yellow +5 = f00 red The repetition starts with +6 = UTC = f0f. As middle position between x00 (0) and xff (255) use x80 (128) as listed at http://www.w3.org/TR/css3-color/#html4 The zones with a 15min offset from a main zone get to use 40 (64) or c0 (192) e.g. +5:45 = ff00c0 (used in Nepal) Even if the colors apart from the Level 1 colors are not desired because they are too difficult to distinguish, one can use the main colors. One can memorize: +1 = CET most parts of the EU = base color of the EU flag +3 = Arab Standard Time, Mecca lies in the +3 zone = green = base color of the flag of Saudi Arabia The one can derive that the color for the zone in between, namely +2, is cyan. Since colors repeat after 6 main zones, +8 will also be cyan. A matrix of colors and offsets can be found at: http://www.tango.info/wiki/UTC_offset_representation_by_6_base_colors If anyone can make a map of the UTC offsets using 6 base colors, not necessarily those that are used in the proposal, I would be happy to see it. Any suggestions for improving the system are welcome. -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com

Sept. 21, 2011

Below are updated proposed changes to the time zone package; the summary: asia Palestine suspends DST during Ramadan in 2011; Gaza and Hebron split in 2011, leading to a new Asia/Hebron zone (thanks to Steffen Thorsen and Alexander Krivenshev). (The different end of DST in Gaza and Hebron in 2008 is also reflected.) europe Belarus adopts permanent DST in 2011 (thanks to Yauhen Kharuzhy, Alexander Bokovoy, Alexander Krivenyshev, and Kirill A. Shutemov). Ukraine adopts permanent DST in 2011 (thanks to Alexander Krivenyshev). "Russia" rules changed to reflect end of use in 2010. "FET" used as abbreviation for Belarus, Ukraine, and western Russia (thanks to Paul Eggert). Also: a comment typo is fixed. northamerica Updated comment on Newfoundland's 2011 change of time of day when DST starts and ends (thanks to Michael Pelley). zone.tab New Asia/Hebron zone (thanks to Alexander Krivenshev).

Ukraine adopts UTC+3 year-round
by Tim Parenti Sept. 20, 2011

Sept. 20, 2011

While I support any effort to create a "unified" abbreviation designation for the new UTC+3 year-round zone to be observed by Belarus and Ukraine (and perhaps even Kaliningrad), I don't think that using "EEST" year-round is necessarily a good idea, especially for zones which are geographically contiguous to others that will be shifting back to EET in October. The similarities in designation could cause confusion in border regions. Furthermore, continuing to call the time "Summer Time" through the winter doesn't make any sense, especially if we're codifying the new zone as UTC+3+0 (standard offset year-round), rather than UTC+2+1, which it seems we are indeed doing. That said, I don't have any better suggestions for a unified designation off the top of my head. I think "UAT" would serve decently for Ukraine's four tz zones, at least unless and until something more "unifying" can be devised. -- Tim Parenti On Tue, Sep 20, 2011 at 09:12, Alexander Bokovoy <abokovoy(a)redhat.com>wrote: > According to > http://w1.c1.rada.gov.ua/pls/zweb_n/webproc4_1?id=&pf3511=40036 > > Ukraine has adopted permanent DST today, September 20th. > > It means we would actually benefit from keeping EEST for Belarus and > Ukraine. >

FW: updated Russian Time Zones - need to correct some districts for Sakha - Yakutia and Sakhalin
by Olson, Arthur David (NIH/NCI) [E] Sept. 20, 2011

Sept. 20, 2011

I'm forwarding this message which didn't seem to make to the list on its own. --ado -----Original Message----- From: Tobias Conradi [mailto:tobias.conradi@gmail.com] Sent: Friday, September 16, 2011 7:12 To: tz(a)lecserver.nci.nih.gov Subject: Re: updated Russian Time Zones - need to correct some districts for Sakha - Yakutia and Sakhalin I wonder whether this 2011 decree really means that tzdata only needs corrections or whether it means that tzdata needs addition of new zones.

proposed time zone package changes (Belarus, Newfoundland, Palestine)
by Arthur David Olson Sept. 20, 2011

Sept. 20, 2011

Here are proposed changes to the time zone package. This set is limited to changes affecting 2011 time stamps, and I'm holding off on changes to Russia pending further information. The executive summary: asia Palestine suspends DST during Ramadan in 2011; Gaza and Hebron split in 2011, leading to a new Asia/Hebron zone (thanks to Steffen Thorsen and Alexander Krivenshev). (The different end of DST in Gaza and Hebron in 2008 is also reflected.) europe Belarus adopts permanent DST in 2011 (thanks to Yauhen Kharuzhy, Alexander Bokovoy, Alexander Krivenyshev, and Kirill A. Shutemov). Given the Belarus change, "Russia" rules changed to reflect end of use in 2010. Also: a comment typo is fixed. northamerica Updated comment on Newfoundland's 2011 change of time of day when DST starts and ends (thanks to Michael Pelley). zone.tab New Asia/Hebron zone (thanks to Alexander Krivenshev). The abbreviation for Belarus is at the moment MINST (MINsk Standard Time). BST (Belarus Standard Time) is a possibility; it is the same as British Summer Time. I'd love to get a report of what's actually in use there (both the name and the abbreviation). If no problems are found, these changes will appear on the ftp site on 2011-09-26. --ado diff -r -c old/asia new/asia *** old/asia Sat Sep 3 08:28:37 2011 --- new/asia Sat Sep 17 14:54:07 2011 *************** *** 1,4 **** ! # @(#)asia 8.65 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,4 ---- ! # @(#)asia 8.67 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 2194,2200 **** --- 2194,2230 ---- # http://www.timeanddate.com/news/time/westbank-gaza-end-dst-2010.html # </a> + # From Steffen Thorsen (2011-08-26): + # Gaza and the West Bank did go back to standard time in the beginning of + # August, and will now enter daylight saving time again on 2011-08-30 + # 00:00 (so two periods of DST in 2011).

Hong Kong problem and BCN timezone(s)
by Jesper Nørgaard Sept. 20, 2011

Sept. 20, 2011

I have found a small problem in the Hong Kong corrections of 2009q. It seems that the Hong Kong government page says that DST was not used in 1977 and 1978, while this is the current tz data: Rule HK 1965 1977 - Apr Sun>=16 3:30 1:00 S Rule HK 1965 1977 - Oct Sun>=16 3:30 0 - Indeed the whole extract of the government web page is still part of the asia file. I would suggest it should be like this Rule HK 1965 1976 - Apr Sun>=16 3:30 1:00 S Rule HK 1965 1976 - Oct Sun>=16 3:30 0 - My other question concerns the timezone America/Santa_Isabel. It seems that several sources imply that all of Baca California Norte is on the same timezone http://www.frontera.info/EdicionEnlinea/Notas/Noticias/13032010/435414.aspx http://www.notisistema.com/noticias/?p=251578 http://www.timeanddate.com/news/time/north-mexico-dst-change.html This is far from authoritative, but at least and indication that BCN might be one single timezone. I wonder if there has been any confirmation of the Santa Isabel timezone in BCN? I am not saying it is not there, I just haven't found any confirmation of it. - Jesper Norgaard Welen

Sep, 15th belarusian council of ministers had decided to abandone DST, so from now belarusian time will be east european(UTC+2)+1. So I've made very trivial patch for tzdata. I've called new belarusian tz as MNSK (derived from Minsk). -- http://375gnu.wordpress.com

Asia/Novosibirsk has Novosibirsk Oblast in the south and Tomsk Oblast in the north. Novosibirsk Oblast has Omsk Oblast in the west and the Altai entities in the east. That is the changes as written down in the Russian Wikipedia lead to contiguous zones at any time, while the current rules in tzdata do not. Omsk Time as in Omsk Oblast, joined by bordering Novosibirsk an eastward expansion, later joined by bordering Altai entities, an eastward expansion, later joined by bordering Tomsk, a northward expansion. Later joined by Kemerovo Oblast, an eastward expansion. This is covered by zone Asia/Novokuznetsk. -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com/tobias_conradi

a comment in C-Eur rules 1944 can be removed

The file tzdate/europe contains this comment regarding the end of DST in Germany 1944: # Whitman gives 1944 Oct 7; go with Shanks & Pottenger. Rule C-Eur 1944 only - Oct 2 2:00s 0 - I have looked up the Reichsgesetzblatt 1944, p.198 which contains the text of the respective decree. Shanks has the correct date and time. I attach a copy. It is very precise because it deals explicitly with the fact that the hour from 2 am to 3 am occurs twice, when the clock is set back from 3 am to 2 am. It says (my translation from German): For the hour of 2 to 3 in the morning of 2nd October 1944, the first occurrence will be called 2A, 2A 1 minute etc until 2A 59 minutes. The second occurrence will be called 2B, 2B 1 minute etc until 2B 59 minutes.

a comment in France rules can be removed
by Alois Treindl Sept. 16, 2011

Sept. 16, 2011

Among the tzdata rules for France one finds these lines: # DSH writes that a law of 1923-05-24 specified 3rd Sat in Apr at 23:00 to 1st # Sat in Oct at 24:00; and that in 1930, because of Easter, the transitions # were Apr 12 and Oct 5. Go with Shanks & Pottenger. Rule France 1922 1938 - Oct Sat>=1 23:00s 0 - Rule France 1923 only - May 26 23:00s 1:00 S Rule France 1924 only - Mar 29 23:00s 1:00 S Rule France 1925 only - Apr 4 23:00s 1:00 S Rule France 1926 only - Apr 17 23:00s 1:00 S Rule France 1927 only - Apr 9 23:00s 1:00 S Rule France 1928 only - Apr 14 23:00s 1:00 S Rule France 1929 only - Apr 20 23:00s 1:00 S Rule France 1930 only - Apr 12 23:00s 1:00 S I have done some source research, and the law of 1923-05-24 really states that. My own translation of the text is: ---- begin quote Article 1 The legal time fixed by the law of 1911 Mar 9 shall each year, following the practical details as given in articles 2,3 and 4, be advanced by sixty minutes, at 23 hours on each last Saturday of March, until the first Saturday of October at 24 hours. But in the case of an understanding with allied neighbour nations, the goverment can shift the first date to the third Saturday of April, and the second date to the third Saturday of September. --- end quote This law was not modified until 1939-09-26. But in practice it was not followed regarding the begin dates. The government issued a decret each year, where it fixed the dates for the particular year. I searched the 'Bulletin des lois de la République française' which are accessible in in digital form via the Bibliotheque National at http://gallica.bnf.fr up to 1931. As an example, I attach the décret for 1930. I think translation isnot needed. From what I have seen as sources between 1916 and 1938, so far, I can confirm that Henri Le Corre is precise and correct, regarding dates and times of change. I can also confirm the '24 hours' always means the end of the day, if a document states something like 'on date X at 24 hours'. Later versions of the décrets are explicit, like the one attached, by saying 'at twenty four hours in the night from 4th to 5th October'. I think the comment currently in the list of Rules, regarding DSH and 1930, can be removed, as Le Corre has been established as reliable for DST rules during this period up to at least 1938.

I'm forwarding this message from Phil Budne, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado -----Original Message----- From: Phil Budne [mailto:phil@ultimate.com] Sent: Thursday, September 15, 2011 5:33 To: tz(a)lecserver.nci.nih.gov Subject: Comments and a question (VTIMEZONE from zoneinfo) Some meta-comments, some comments, and a question: The page at http://www.twinsun.com/tz/tz-link.htm says: "Please send corrections to this web page to the time zone mailing list." Reading the directory at http://www.twinsun.com/tz/ shows the html file hasn't changed since 2008-06-30. Until I checked the twinsun.com WHOIS entry and saw it's owned by (current tz editor) Paul Eggert, I was wondering about whether to trust the page at all! At some point I lost the twinsun URL, and couldn't find a link in any obvious places, like Wikipedia, or ftp://elsie.nci.nih.gov/pub/ So my first comment is, the tz-link page needs more meta information (eg; date of last change & author). If the tz-link page is being maintained, there should be visible links to it in obvious places, and if it isn't, the page should have a comment reflecting this. It would be useful to have a .html file at ftp://elsie.nci.nih.gov/pub/ with current information, a link to current information, or at least a link to dated, but possibly useful information! Since this is my first public comment on the TZ list, let me express my long time admiration (I remember 4BSD when the rules were compiled into libc, and systems like TOPS-20, where they were in the "kernel") to all, past and present who have endeavored to make sense of this herculian problem (the proportions and magnitude of which are so truely perverse, that they could only have been made by mankind which, unlike nature, has no collective ability (or perhaps more succinctly or single authority powerful enough) to conform to Occam's Razor. As a side comment, there's nothing more Talmudic than commentary on commentary, so the appreciation of the tzdata files at http://blog.jonudell.net/2009/10/23/a-literary-appreciation-of-the-olsonzon… as talmudic is especially apropos! Finally, I know it's unlikely to change, but I find the fact that the tzdata tar files extract to the current directory (as opposed to creating a new directory) to be, to be kind "quaint". And I'll confess, I have a project that's so dated (a 1990's "finger" program, from back when exposing personal information on the Internet wasn't considered a problem) whose tar file is still available on my FTP server that has the same "charming" behavior of unloading it's contents into an unsuspecing extractor's current working directory. On to non-meta commentary: The link for "vzic": http://www.dachaplin.dsl.pipex.com/vzic/ is dead. There is a vzic project at: http://vzic.sourceforge.net/ and http://vzic.sourceforge.net/ Registered in 2006, and unchanged since 2010. http://code.google.com/p/tzurl/ says "This project is a fork of the vzic project." and appears to be under active development/maintenance. Related pages/projects are: http://tzurl.org/ which supplies "the latest Olson DB timezone definitions in iCalendar format" (generated using "tzurl") And "ical4j" http://code.google.com/p/ical4j/ "A suite of Java libraries for managing iCalendar and vCard data" and http://wiki.modularity.net.au/ical4j/index.php?title=Main_Page Which at http://wiki.modularity.net.au/ical4j/index.php?title=Timezones reads: iCal4j provides it's own TimeZone implementation as opposed to using the default Java timezone implementation. This is to ensure that all timezones in iCal4j can be accurately represented using a VTIMEZONE component in calendar data. The iCal4j timezone is essentially an implementation of java.util.TimeZone that is backed by a net.fortuna.ical4j.component.VTimeZone instance. Whilst a timezone instance may be created explicitly, typical usage is to obtain a TimeZoneRegistry instance and retrieve the timezone instance from the registry. And FINALLY, a question: Has anyone heard of code that reads binary tz data, and outputs VTIMEZONE info? Extracting rules for a specific year is sufficient. I can SWEAR I once saw an "unzic" program, but maybe I'm having a new bout of a particular form of senior moment I've experienced before, where I remember things that have never happened. We've been using vzic, but it isn't a great solution since RedHat Linux doesn't supply an RPM for the timezone source files that vzic needs to run, so we're stuck having to track version of the tzdata RPM on the specific version of RedHat that the product installs on. I got involved because I felt the seismic activity when the problem landed on the desk of an engineer without sufficient experience to grasp of the enormity of the hairball that had just hit him. Thanks Phil

At some point I lost the twinsun URL, and couldn't find a link in any obvious places, like Wikipedia, or ftp://elsie.nci.nih.gov/pub/ So my first comment is, the tz-link page needs more meta information (eg; date of last change & author). If the tz-link page is being maintained, there should be visible links to it in obvious places, and if it isn't, the page should have a comment reflecting this. It would be useful to have a .html file at ftp://elsie.nci.nih.gov/pub/ with current information, a link to current information, or at least a link to dated, but possibly useful information! Since this is my first public comment on the TZ list, let me express my long time admiration (I remember 4BSD when the rules were compiled into libc, and systems like TOPS-20, where they were in the "kernel") to all, past and present who have endeavored to make sense of this herculian problem (the proportions and magnitude of which are so truely perverse, that they could only have been made by mankind which, unlike nature, has no collective ability (or perhaps more succinctly or single authority powerful enough) to conform to Occam's Razor. As a side comment, there's nothing more Talmudic than commentary on commentary, so the appreciation of the tzdata files at http://blog.jonudell.net/2009/10/23/a-literary-appreciation-of-the-olsonzon… as talmudic is especially apropos! Finally, I know it's unlikely to change, but I find the fact that the tzdata tar files extract to the current directory (as opposed to creating a new directory) to be, to be kind "quaint". And I'll confess, I have a project that's so dated (a 1990's "finger" program, from back when exposing personal information on the Internet wasn't considered a problem) whose tar file is still available on my FTP server that has the same "charming" behavior of unloading it's contents into an unsuspecing extractor's current working directory. On to non-meta commentary: The link for "vzic": http://www.dachaplin.dsl.pipex.com/vzic/ is dead. There is a vzic project at: http://vzic.sourceforge.net/ and http://vzic.sourceforge.net/ Registered in 2006, and unchanged since 2010. http://code.google.com/p/tzurl/ says "This project is a fork of the vzic project." and appears to be under active development/maintenance. Related pages/projects are: http://tzurl.org/ which supplies "the latest Olson DB timezone definitions in iCalendar format" (generated using "tzurl") And "ical4j" http://code.google.com/p/ical4j/ "A suite of Java libraries for managing iCalendar and vCard data" and http://wiki.modularity.net.au/ical4j/index.php?title=Main_Page Which at http://wiki.modularity.net.au/ical4j/index.php?title=Timezones reads: iCal4j provides it's own TimeZone implementation as opposed to using the default Java timezone implementation. This is to ensure that all timezones in iCal4j can be accurately represented using a VTIMEZONE component in calendar data. The iCal4j timezone is essentially an implementation of java.util.TimeZone that is backed by a net.fortuna.ical4j.component.VTimeZone instance. Whilst a timezone instance may be created explicitly, typical usage is to obtain a TimeZoneRegistry instance and retrieve the timezone instance from the registry. And FINALLY, a question: Has anyone heard of code that reads binary tz data, and outputs VTIMEZONE info? Extracting rules for a specific year is sufficient. I can SWEAR I once saw an "unzic" program, but maybe I'm having a new bout of a particular form of senior moment I've experienced before, where I remember things that have never happened. We've been using vzic, but it isn't a great solution since RedHat Linux doesn't supply an RPM for the timezone source files that vzic needs to run, so we're stuck having to track version of the tzdata RPM on the specific version of RedHat that the product installs on. I got involved because I felt the seismic activity when the problem landed on the desk of an engineer without sufficient experience to grasp of the enormity of the hairball that had just hit him. Thanks Phil

Theory - zone creation description wrong
by Mr tobias conradi Sept. 14, 2011

Sept. 14, 2011

As far as I can see tzcode2011i/Theory is missing the fact that for each country at least one zone is created. I.e. maybe Luxembourg and France may have their own zones not due to different timestamp observance since 1970-01-01 00:00:00 UTC but simply due to the fact that they are different countries. CURRENT "the world is partitioned into regions whose clocks all agree about time stamps that occur after the somewhat-arbitrary cutoff point of the POSIX Epoch (1970-01-01 00:00:00 UTC). For each such region, the database records all known clock transitions, and labels the region with a notable location." PROPOSED "the world is partitioned into regions, named zones, whose clocks all agree about time stamps that occur after the somewhat-arbitrary cutoff point of the POSIX Epoch (1970-01-01 00:00:00 UTC). Additional for each country at least one zone is created. For each zone, the database records all known clock transitions, and labels the zone with a notable location. -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin, Germany http://tobiasconradi.com

I think people are free to submit proposals at any time. > The practice for each zone in tzdata is that also the complete history > from the beginning of standard time must be included in the zone file. 1) Alois Treindl 2011-08-30 14:40:48 GMT: "I have compiled a complete timezone history of Germany." http://article.gmane.org/gmane.comp.time.tz/3951 Buesingen is part of Germany says http://www.buesingen.de/ "Büsingen am Hochrhein ist, wenn auch ringsum von Schweizer Hoheitsgebiet umgeben, deutsches Hoheitsgebiet" 2) I see no proof that it is practice "that complete history from the beginning of standard time must be included in the zone file." 3) I see no statement in the Theory file nor in README that would require such a practice. To the contrary, Theory file says: "As noted in the README file, the tz database is not authoritative (particularly not for pre-1970 time stamps), and it surely has errors. Corrections are welcome and encouraged." README says: "The information in the time zone data files is by no means authoritative; the files currently do not even attempt to cover all time stamps before 1970, and there are undoubtedly errors even for time stamps since 1970. If you know that the rules are different from those in a file, by all means feel free to change file (and please send the changed version to tz(a)elsie.nci.nih.gov for use in the future)." 4) I did not edit the file(s) in question since I don't know how to structure it. I hope someone with more knowledge can help to fix the current error for 1980. Additional pre-1970 imprecisions remain open to be fixed, the fix I propose does not hinder future progress.

US Mountain/Central border at Fort Pierre SD
by Steve Jones Sept. 12, 2011

Sept. 12, 2011

If I might seek the wisdom of the list on a minor topic: The current Mountain/Central boundary in the most recent official US DOT description (49CFR71.7, http://goo.gl/tqBou) has the border running right through Fort Pierre South Dakota. Here is the relevant text: > From the junction of the North Dakota-South Dakota boundary with > the Missouri River southerly along the main channel of that river > to the crossing of the original Chicago & North Western Railway > near Pierre; thence southwesterly to the northern boundary of Jones > County at the northeast corner of the NE 1, Sec. 6, T. 2 N., R. 30 > E. [note: that's about 44.18635, -100.54646) That makes a straight line from the railroad bridge north of town to 44.18635, -100.54646, this line not making much sense in the context of what's on the ground. A second-hand recent conversation with a Stanley County SD official was relayed to me, including the following: >...The person with whom I spoke said the official dividing line is >the Bad River, which makes more >sense than bisecting Fort Pierre. ... The communities along the >Bad River are so tiny (several houses each) that they don't have >official policies. The person with whom I spoke assumed they would >use Central Time because aside from Fort Pierre, there's no >significant populated place that's even close. There are several common sense border adjustments I could make here and probably be more accurate than the DOT (with regards to what a traveler would encounter in the area). Something like a line from the southern end of the dam at Lake Oahe southward to the Bad River, then following the Bad River soutwesterly to the northern border of Jones County... (and from that point rejoining the DOT description). I would prefer to use some authoritative reference - if possible. Any advice on how to proceed? All I can think of is to try a reference librarian in Pierre. Cheers, Steve Jones

Theory - zone name, zone creation, zone lifetime
by Mr tobias conradi Sept. 12, 2011

Sept. 12, 2011

Theory reads: To represent this data, the world is partitioned into regions whose clocks all agree about time stamps that occur after the somewhat-arbitrary cutoff point of the POSIX Epoch (1970-01-01 00:00:00 UTC). Issue: 1) Where are these regions listed? The only lists of geographical areas I could find are: - the zones in zone.tab - (current) countries in iso3166.tab Theory reads: Use ISO 3166 (see the file iso3166.tab) to help decide whether something is a country. [...] or when locations change countries (e.g. Hong Kong from UK colony to China) Issue: 1) "help to decide" - decision process is undefined. 2) Hong Kong is listed in iso3166.tab as HK.For the purpose of zone creation is it 2a) a country,then it is confusing to say it changed country, or 2b) is it part of China (CN) then it is confusing to mark it with HK 3) In case HK and one of the zones in CN observed the same time since 1970, and that HK is not a country, would there be a merge and would one zone be dropped from zone.tab and any corresponding pre-1970 history be deleted? Theory reads: Within a file name component, use only ASCII letters Issue: 1) It is not defined what the term "file name component" refers to in the context of zone naming. Theory reads: E.g. prefer `Paris' to `France', since France has had multiple time zones. Issue: 1) It does not matter what zones France "had" in the past. 2) It may matter that Europe/Paris might be split in the future. 3) There is no proof in zone.tab that France had multiple time zones at all, there is only one line marked "FR": FR+4852+00220Europe/Paris -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin, Germany http://tobiasconradi.com

The file... ftp://elsie.nci.nh.gov/pub/tzdata2011j.tar.gz ...is now available; this reflects the changes circulated recently on the times zone mailing list (contemporary changes for Samoa; past changes for Kenya, Uganda, and Tanzania); there are also two spelling corrections to comments in the australasia file (with thanks to Christos Zoulas).

Texas timezone history

Sept. 8, 2011

I have reviewed the Texas timezone history before 1970. I attach my result, which proposes two additional Texas zones America/Houston and Amerca/Amarillo. I think there is an error in the current tzdata/northamerica file regarding Texas. It claims that Texas follows America/Chicago. But this is not the case as Texas had no DST in 1936, as Chicago did. Please check my data and my typing, as I am a bad typist.

Russian Time Zone
by Wong Ren Sept. 8, 2011

Sept. 8, 2011

Hi, The latest 2011i tzdata does not have the Russian time change described by Alexander Krivenyshev: "DRAFT DECISION OF THE GOVERNMENT OF Russian Federation "On the composition of the territories that make up each time zone, and the procedure of calculation of time within time zones, and the Repeal of certain resolutions of the Government of the Russian Federation on August 8, 2011" On October 30, 2011, at 02:00 local time the following new time calculations will be applied: Irkutsk region will use the 5th Russian time zone (MSK +4) Republic of Sakha (Yakutia) will use the 7th Russian time zone (MSK +6) Primorsky Krai (Vladivostok) will use the 7th Russian time zone (MSK +6)" It is not clear to me what's the exact impact for these additional changes to the original proposal . I have summarized what I think are the changes in the table below, could someone verify?

Alabama timezone history
by Jules Descartes Sept. 6, 2011

Sept. 6, 2011

I have started reviewing pre-1970 US timezone history. The information is so complex that it is best approached state by state. I have started alphabetically with Alabama, but will probably continue with some mixture like - most populous states first - simplest states first For Alabama history my first draft proposes ten zones. This is more detailed than Shanks, wo distinguished seven areas. It is only a first step. Newspaper archive research (sadly) reveals that there are far more complex details involved in a complete history, and many questions about extension of zones can probably never be answered because there are not enough precise records. I have made a map, together with the help of colleagues, and uploaded it to wikimedia, as I am not sure whether image files work in this mailing list. Certainly we save bandwidth, as in the old times. License question: For now I have decided to place my work under the widest possible Creative Commons. This differs from the Public Domain license only in so far, as sources need to be quoted. Aside of that the use of the information is free, also within commercial projects of any kind. Please check and proof read the proposed zones. I am a bad typist.

RE: proposed time zone package changes (South Sudan, Samoa, Newfoundland...)
by Arthur David Olson Sept. 3, 2011

Sept. 3, 2011

As a reminder, here are the changes proposed last week: africa Add Africa/Juba (South Sudan) zone. australasia Samoa skips over 2011-12-30 (thanks to David Zuelke and Mark Sim-Smith). europe Use KALT as abbreviation for Europe/Kalinigrad from spring 2011 forward (thanks to Yoshito Umaoka). northamerica Newfoundland changes time of day for DST start and end to 2:00 a.m. starting fall 2011 and forward (thanks to Michael Pelley). Change America/Resolute use of EST to 2006-2007 only (thanks to Chris Walton). Assume Metlakatla abandoned use of daylight saving as a result of its 1983 vote. Avoid unnecessary use of US rule in America/Honolulu; fix two typos in America/Honolulu comments. iso3166.tab Add SS (South Sudan) entry. zone.tab Change America/Resolute entry to Central Standard Time. (thanks to Chris Walton). Add SS (South Sudan, Africa/Juba) entry. And here are additional changes being proposed today: Makefile Remove itca.jpg from distribution (thanks to Paul Eggert) australasia Remove unneeded "+" from "+13:00" in Samoa entry (thanks to Tim Parenti) iso3166.tab Fix comment regarding ISO 3166 (thanks to Philip Newton) newstrftime.3 Remove incorrect status comment (thanks to Paul Eggert) northamerica Adjust America/Goose_Bay as well as America/St_Johns from fall 2011 forward (thanks to Chris Walton) I expect to update the ftp versions on 2011-08-29. --ado diff -r -c old/Makefile new/Makefile *** old/Makefile Thu Apr 14 12:42:47 2011 --- new/Makefile Wed Aug 24 07:46:28 2011 *************** *** 1,5 **** # <pre> ! # @(#)Makefile 8.10 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)Makefile 8.11 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 270,276 **** DATA= $(YDATA) $(NDATA) $(SDATA) $(TABDATA) leapseconds yearistype.sh WEB_PAGES= tz-art.htm tz-link.htm MISC= usno1988 usno1989 usno1989a usno1995 usno1997 usno1998 \ ! itca.jpg $(WEB_PAGES) checktab.awk workman.sh \ zoneinfo2tdf.pl ENCHILADA= $(DOCS) $(SOURCES) $(DATA) $(MISC) --- 270,276 ---- DATA= $(YDATA) $(NDATA) $(SDATA) $(TABDATA) leapseconds yearistype.sh WEB_PAGES= tz-art.htm tz-link.htm MISC= usno1988 usno1989 usno1989a usno1995 usno1997 usno1998 \ ! $(WEB_PAGES) checktab.awk workman.sh \ zoneinfo2tdf.pl ENCHILADA= $(DOCS) $(SOURCES) $(DATA) $(MISC) diff -r -c old/africa new/africa *** old/africa Wed Jun 15 06:43:13 2011 --- new/africa Wed Aug 17 13:47:14 2011 *************** *** 1,5 **** # <pre> ! # @(#)africa 8.31 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)africa 8.32 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 956,961 **** --- 956,966 ---- Zone Africa/Khartoum 2:10:08 - LMT 1931 2:00 Sudan CA%sT 2000 Jan 15 12:00 3:00 - EAT + + # South Sudan + Zone Africa/Juba 2:06:24 - LMT 1931 + 2:00 Sudan CA%sT 2000 Jan 15 12:00 + 3:00 - EAT # Swaziland # Zone NAME GMTOFF RULES FORMAT [UNTIL] diff -r -c old/australasia new/australasia *** old/australasia Wed Jun 15 06:53:04 2011 --- new/australasia Wed Aug 17 17:27:48 2011 *************** *** 1,5 **** # <pre> ! # @(#)australasia 8.23 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)australasia 8.25 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 529,540 **** # Margaret Fruean ACTING CHIEF EXECUTIVE OFFICER MINISTRY OF COMMERCE, # INDUSTRY AND LABOUR 28th February 2011 Zone Pacific/Apia 12:33:04 - LMT 1879 Jul 5 -11:26:56 - LMT 1911 -11:30 - SAMT 1950 # Samoa Time -11:00 - WST 2010 Sep 26 -11:00 1:00 WSDT 2011 Apr 2 4:00 ! -11:00 - WST # Solomon Is # excludes Bougainville, for which see Papua New Guinea --- 529,585 ---- # Margaret Fruean ACTING CHIEF EXECUTIVE OFFICER MINISTRY OF COMMERCE, # INDUSTRY AND LABOUR 28th February 2011 + # From David Zuelke (2011-05-09): + # Subject: Samoa to move timezone from east to west of international date line + # + # <a href="http://www.morningstar.co.uk/uk/markets/newsfeeditem.aspx?id=138501958347963"> + # http://www.morningstar.co.uk/uk/markets/newsfeeditem.aspx?id=138501958347963 + # </a> + + # From Mark Sim-Smith (2011-08-17): + # I have been in contact with Leilani Tuala Warren from the Samoa Law + # Reform Commission, and she has sent me a copy of the Bill that she + # confirmed has been passed...Most of the sections are about maps rather + # than the time zone change, but I'll paste the relevant bits below.

Tonga standard time changes, attn. Paul Eggert
by Alois Treindl Sept. 2, 2011

Sept. 2, 2011

attention Paul Eggert: I am reading through the comments for zone Pacific/Tonga and there you write on 2006-03-22: ... go with Mundell where "Mundell" means his article by Don Mundell http://www.tongatapu.net.to/tonga/homeland/timebegins.htm In reading this article, I cannot see where he places the transition from standard meridian 185°e (12:20h) to 195°e (13:00h) into the year 1999. What I read is that he talks about the change in New Zealand timezone from meridian 172.5°e (11:30h) to 180°e (12:00h) on 1946-jan-01, and that the Crown prince Tungi, wanted to maintain the 50 minutes difference to New Zealand. But it appears that no change was made then, in 1946, and Tonga now had only a 20 min difference to New Zealand. I cannot see how you derive a change in 1999 from what Mundell writes. Please clarify. Shanks has this change in 1968, but as usual he gives no source. PS: does anyone know of a way to get access to old IATA SSIM manuals? I rember those being voluminous books which travel agents used to look up flight schedules. For several years, I used to collect older copies of these manuals from a travel agent and use them to look up timezones, as they were documented for each airport, together with begin/end dates for DST if such a change fell into the two-month period a manual covered. I had a collection of many years from the late 1970ies and the 1980ies, but threw them out when I got hold of Shanks' books. Now I would love to check some information in them again, but so far have been unable to find where copies are held in an archive.

completed timezone history of Germany
by Alois Treindl Aug. 30, 2011

Aug. 30, 2011

I have compiled a complete timezone history of Germany. It defines 10 additional zones for parts of Germany which had a timezone history different from Europe/Berlin Two of these zones refer to areas belonging to Poland since 1945. The processing of the zone file with zic requires that zic is patched with the 'follow rule' patch I had submitted for review on 25 August.

corrected DST data Switzerland 1941 and 1942, final report
by Alois Treindl Aug. 25, 2011

Aug. 25, 2011

Hello I have researched the DST usage in Switzerland during the 1940ies. As I wrote in an earlier message, I suspected the current tzdata values to be wrong. This is now verified. I have found copies of the original ruling by the Swiss Federal government, in 'Eidgenössische Gesetzessammlung 1941 and 1942' (Swiss federal law collection) and attach GIF copies of the two pages for 1941. DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am. DST began on Monday, 4 May 1942 at 01:00 am DST ended on Monday, 5 Oct 1942 at 02:00 am There was no DST in 1940, I have checked the law collection carefully. It is also indicated by the fact that the 1942 entry in the law collection points back to 1941 as a reference, but no reference to any other years are made. Newspaper articles I have read in the archives on 6 May 1941 reported about the introduction of DST (Sommerzeit in German) during the previous night as an absolute novelty, because this was the first time that such a thing had happened in Switzerland. I have also checked 1916, because one book source (Gabriel, Traite de l'heure dans le monde) claims that Switzerland had DST in 1916. This is false, no official document could be found. Probably Gabriel got misled by references to Germany, which introduced DST in 1916 for the first time. The tzdata rules for Switzerland must be changed to: Rule Swiss 1941 1942 - May Mon>=1 1:00 1:00 S Rule Swiss 1941 1942 - Oct Mon>=1 2:00 0 - The 1940 rules must be deleted. One further detail for Switzerland, which is probably out of scope for most users of tzdata: The zone file Zone Europe/Zurich 0:34:08 - LMT 1848 Sep 12 0:29:44 - BMT 1894 Jun #Bern Mean Time 1:00 Swiss CE%sT 1981 1:00 EU CE%sT describes all of Switzerland correctly, with the exception of the Cantone Geneve (Geneva, Genf). Between 1848 and 1894 Geneve did not follow Bern Mean Time but kept its own local mean time. To represent this, an extra zone would be needed. Two GIF files are attached. best regards Alois -- || Alois Treindl, Astrodienst AG, mailto:alois@astro.com || Zollikon/Zurich, Switzerland || Free astrological charts at http://www.astro.com/ || SWISS EPHEMERIS Free Edition at http://www.astro.com/swisseph/

3 Russian regions may change time zones on October 30, 2011
by Alexander Krivenyshev Aug. 22, 2011

Aug. 22, 2011

According to a government proposal published a few weeks ago on the Ministry of Industry and Trade of the Russian Federation Web site, 3 Russian regions may change time zones this autumn: Vladivostok (Primorsky region) – Move from MSK+7 to MSK +6 Sakha (Yakutia) – 3 current time zones collapsed into a single zone MSK+6 Irkutsk region – Move from MSK+5 to MSK +4 This document confirms that Moscow will use UTC+4 year round and all other regions except those listed above will keep current Summer time year round. Below are a few translated citations from original Russian government proposal: DRAFT DECISION OF THE GOVERNMENT OF Russian Federation “On the composition of the territories that make up each time zone, and the procedure of calculation of time within time zones, and the Repeal of certain resolutions of the Government of the Russian Federation on August 8, 2011” On October 30, 2011, at 02:00 local time the following new time calculations will be applied: Irkutsk region will use the 5th Russian time zone (MSK +4) Republic of Sakha (Yakutia) will use the 7th Russian time zone (MSK +6) Primorsky Krai (Vladivostok) will use the 7th Russian time zone (MSK +6) This draft proposal was signed by Russian Prime Minister Vladimir Putin. The original draft proposal was posted and is currently unavailable to view from the official government Web site. However, there is ongoing Russian media coverage and Worldtimezone.com was able to save the original posting. It can be viewed at the following link (use Google translation from Russian): http://www.worldtimezone.com/dst_news/dst_news_russia33.html Worldtimezone.com will keep you posted as new developments become available.

Re: China time zone
by An Yang Aug. 18, 2011

Dear Arthur, Thanks a lot. At first, let me show you some data: Population of Beijing in 2011 is 22,634,722, data from http://www.trueknowledge.com/q/population_of_beijing_in_2011 And population of Shanghai in 2011 is 22,447,529, data from http://www.trueknowledge.com/q/population_of_shanghai_in_2011 And of cause, you can check the population of Beijing and Shanghai in 1996, Beijing is 2,069,722, and Shanghai is 1,188,721. If your data source is http://www.world-gazetteer.com/wg.php?x=1263073253&men=gcis&lng=en&des=game… and http://www.citypopulation.de/world/Agglomerations.html What I can say, the data is wrong absolutely. The following is the data from the China Gov (Chinese only): http://www.shanghai.gov.cn/shanghai/node2314/node2319/node12344/u26ai25463.… http://www.bjstats.gov.cn/rkpc_6/pcsj/201105/t20110506_201580.htm All of these data is different, what should we trust? Let me try to explain it, frankly say, it's difficult to count the exact population of a city which have more than 20,000,000, especially in China. The population data from government, it just include the people who have the locale ID ( hukou ), do not include people without locale ID (hukou). So maybe 20-30% people lost, I think the data from http://www.trueknowledge.com is more accurate, which reflect the real number of people who live in the city. My conclusion is both Beijing and Shanghai are big city in China, and have almost the similar populations. According to the rule: Among locations with similar populations, pick the best-known location, e.g. prefer `Rome' to `Milan'. I think the best-known location is Beijing, no matter from Chinese view or from the foreigner's view. I have read all the messages about Beijing Time in ftp://elsie.nci.nih.gov/pub/tzarchive.gz, and notice that all the voice from China is the same, Beijing should represent China. So trust the people who live there and use Beijing time everyday maybe the best choice.

proposed time zone package changes (South Sudan, Samoa, Newfoundland...)
by Arthur David Olson Aug. 17, 2011

Aug. 17, 2011

Proposed changes to the time zone package appear at the end of this message; here's the executive summary: africa Add Africa/Juba (South Sudan) zone. australasia Samoa skips over 2011-12-30 (thanks to David Zuelke and Mark Sim-Smith). europe Use KALT as abbreviation for Europe/Kalinigrad from spring 2011 forward (thanks to Yoshito Umaoka). northamerica Newfoundland changes time of day for DST start and end to 2:00 a.m. starting fall 2011 and forward (thanks to Michael Pelley). Change America/Resolute use of EST to 2006-2007 only (thanks to Chris Walton). Assume Metlakatla abandoned use of daylight saving as a result of its 1983 vote. Avoid unnecessary use of US rule in America/Honolulu; fix two typos in America/Honolulu comments. iso3166.tab Add SS (South Sudan) entry. zone.tab Change America/Resolute entry to Central Standard Time. (thanks to Chris Walton). Add SS (South Sudan, Africa/Juba) entry. Providentially South Sudan's largest is also its capital city; I hope there's no zone naming controversy. I plan to update the ftp site on 2011-08-29 with these changes (modulo any corrections provided by folks on the time zone mailing list). --ado diff -r -c old/africa new/africa *** old/africa Wed Jun 15 06:43:13 2011 --- new/africa Wed Aug 17 13:47:14 2011 *************** *** 1,5 **** # <pre> ! # @(#)africa 8.31 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)africa 8.32 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 956,961 **** --- 956,966 ---- Zone Africa/Khartoum 2:10:08 - LMT 1931 2:00 Sudan CA%sT 2000 Jan 15 12:00 3:00 - EAT + + # South Sudan + Zone Africa/Juba 2:06:24 - LMT 1931 + 2:00 Sudan CA%sT 2000 Jan 15 12:00 + 3:00 - EAT # Swaziland # Zone NAME GMTOFF RULES FORMAT [UNTIL] diff -r -c old/australasia new/australasia *** old/australasia Wed Jun 15 06:53:04 2011 --- new/australasia Wed Aug 17 11:55:06 2011 *************** *** 1,5 **** # <pre> ! # @(#)australasia 8.23 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)australasia 8.24 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 529,540 **** # Margaret Fruean ACTING CHIEF EXECUTIVE OFFICER MINISTRY OF COMMERCE, # INDUSTRY AND LABOUR 28th February 2011 Zone Pacific/Apia 12:33:04 - LMT 1879 Jul 5 -11:26:56 - LMT 1911 -11:30 - SAMT 1950 # Samoa Time -11:00 - WST 2010 Sep 26 -11:00 1:00 WSDT 2011 Apr 2 4:00 ! -11:00 - WST # Solomon Is # excludes Bougainville, for which see Papua New Guinea --- 529,585 ---- # Margaret Fruean ACTING CHIEF EXECUTIVE OFFICER MINISTRY OF COMMERCE, # INDUSTRY AND LABOUR 28th February 2011 + # From David Zuelke (2011-05-09): + # Subject: Samoa to move timezone from east to west of international date line + # + # <a href="http://www.morningstar.co.uk/uk/markets/newsfeeditem.aspx?id=138501958347963"> + # http://www.morningstar.co.uk/uk/markets/newsfeeditem.aspx?id=138501958347963 + # </a> + + # From Mark Sim-Smith (2011-08-17): + # I have been in contact with Leilani Tuala Warren from the Samoa Law + # Reform Commission, and she has sent me a copy of the Bill that she + # confirmed has been passed...Most of the sections are about maps rather + # than the time zone change, but I'll paste the relevant bits below.

Which tzdata zones have complete pre-1970 history?
by Alois Treindl Aug. 17, 2011

Aug. 17, 2011

With some colleagues who are like myself interested in a complete pre-1970 timezone history in a tzdata compatible file format, I have started a project whose goals is the following: a) complete existing tzdata zone files with incomplete pre-1970 history, so that they become historically complete. b) create additional tzdata zone files which represent zones where tzdata currently fails to differentiate between areas with different pre-1970 history. The motivation for this effort is that astrology needs complete timezone histories, for each point on the globe where registered birth data are likely to exist. I am aware that the design goal of tzdata is only to represent complete and correct timezone information beginning with 1 January 1970. I do not question this design goal. Still, there is a community of tzdata users who need more than that, and who are missing an open source database with complete timezone histories. For example, Switzerland needs an extra zone Europe/Geneva to represent Geneva timezone between 1851 and 1894. Germany needs about 13 different zones to represent the timezone history of different parts of the country. The matter there is even mor complicated because Germany changed size repeatedly in the 19th and 20th century, parts were added or removed from it and assigned to other countries. By the way, it is excellent that tzdata zone names are based on cities and not on countries, as this avoids a lot of political issues. I think it would be a good start investigating for which of the approx. 400 tzdata zones the pre-1970 history can be considered complete and correct. We have no absolute reliable measure what 'complete and correct' means. But a comparison with a recent revision of Shanks/Pottenger American and International atlas would already serve to a large extent. As a working definition I propose: Those tzdata zones whose history details are equivalent or better than the corresponding history lists by Shanks & Pottenger should be considered complete and correct. ---------------------------- Example: Switzerland Switzerland is not historically complete in tzdata. tzdata zone Europe/Zurich is correct, but a separate zone Europe/Geneva is missing. The canton of Geneva had Geneva mean time 6E0915 between 1851 and the introduction of standard time on 1 June 1894 (SOURCE: GABRIEL, TRAITE DE L'HEURE DANS LE MONDE, edition 1991) Shanks/Pottenger have a separate table for this canton, but it contains a small error as well: it assigns LMT until 1894, while in fact it should be Geneva city observatory mean time (24m37s east of Greenwich) between 1851 and 1894. The error is small because this canton is not big, and the most distance any other town has from the Geneva meridian is 4 minutes of arc.

Re: colloquium on Future of UTC
by Yann Droneaud Aug. 17, 2011

Aug. 17, 2011

Hi, Regarding this subject, the IERS is running a survey about UTC definition change. The survey was announced in the latest C bulletin (42) available at ftp://hpiers.obspm.fr/iers/bul/bulc/bulletinc.42 " IMPORTANT: After years of discussions, a proposal to fundamentally redefine UTC will come to a conclusive vote in January 2012 at the ITU-R in Geneva. This proposal would halt the intercalary adjustments known as leap seconds that maintain UTC as a form of Universal Time. The Earth Orientation Center of the IERS organizes a survey online with the objective to find out the strength of opinion for maintaining or changing the present system. Link to the questionnaire: http://hpiers.obspm.fr/eop-pc/index.php?index=questionnaire Your response is appreciated before 30 August 2011 " Regards. -- Yann Droneaud

colloquium on Future of UTC
by Steve Allen Aug. 17, 2011

Aug. 17, 2011

On behalf of the co-chairs I announce a colloquium about the implications of possible changes to the definition of UTC which is scheduled for a vote by delegates to the Radiocommunication Assembly in January. The draft under consideration by the ITU-R would redefine the notions of time and calendar day in ways that would have broad side effects. The website for the colloquium is http://futureofutc.org/ Abstracts already received include contributions from national observatories, international agencies, geophysics and navigation communities. Software and operating systems remain underrepresented. I invite contributions from members of the time zone community and anyone who may have code, systems, or products which could be affected by changes in the definition of the radio broadcast time signals which underly them. -- Steve Allen <sla(a)ucolick.org> WGS-84 (GPS) UCO/Lick Observatory--ISB Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m

FW: Fingerprinting timezones

I'm forwarding this message from Conrad Irwin, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado -----Original Message----- From: Conrad Irwin [mailto:conrad.irwin@gmail.com] Sent: Monday, August 08, 2011 7:59 To: tz(a)lecserver.nci.nih.gov Subject: Fingerprinting timezones Hello there, Thank you for the timezone database - it is a phenomenal resource. The problem I would like to solve is that of having to ask a user of a web-app for their timezone. While there is no way to directly query for the user's timezone, the javascript engine in their web-browser is capable of telling me the offset from UTC at any date. It seems like, by selecting some number of dates to query, I should be able to gather enough information to uniquely identify any given timezone (or at least make a very good guess for a large proportion of the user-base). Before I embarked on doing this, I wanted to ask if anyone has seen a similar attempt in the past? Are there some "gotchas" that mean that this isn't actually as feasible as I naïvely hope? Conrad

Fingerprinting timezones
by Conrad Irwin Aug. 8, 2011

Aug. 8, 2011

Hello there, Thank you for the timezone database — it is a phenomenal resource. The problem I would like to solve is that of having to ask a user of a web-app for their timezone. While there is no way to directly query for the user's timezone, the javascript engine in their web-browser is capable of telling me the offset from UTC at any date. It seems like, by selecting some number of dates to query, I should be able to gather enough information to uniquely identify any given timezone (or at least make a very good guess for a large proportion of the user-base). Before I embarked on doing this, I wanted to ask if anyone has seen a similar attempt in the past? Are there some "gotchas" that mean that this isn't actually as feasible as I naïvely hope? Conrad

America/Resolute
by Chris Walton Aug. 6, 2011

Aug. 6, 2011

Back in 2007 I initiated the creation of a new "zone file" for Resolute Bay. Resolute Bay is a small community located about 900km north of the Arctic Circle. The zone file was required because Resolute Bay had decided to use UTC-5 instead of UTC-6 for the winter of 2006-2007. http://www.nnsl.com/frames/newspapers/2006-11/nov13_06none.html According to new information which I received last week, Resolute Bay went back to using UTC-6 in the winter of 2007-2008. This new information conflicts with information I received in November 2008. Assuming the new information is correct, a change is required for "America/Resolute" Details are below. Sorry this post is so long. #---------------------------------------------------------- On March 11/2007 most of Canada went onto daylight saving. On March 14/2007 I phoned the Resolute Bay hamlet office to do a "time check". I talked to somebody that was both knowledgeable and helpful. I was able to confirm that Resolute Bay was still operating on UTC-5. It was explained to me that Resolute Bay had been on the Eastern Time zone (EST) in the winter, and was now back on the Central Time zone (CDT). i.e. the time zone had changed twice in the last year but the clocks had not moved. The residents had to know which time zone they were in so they could follow the correct TV schedule. #---------------------------------------------------------- I did not contact anybody in Resolute Bay for the next year and a half. #---------------------------------------------------------- On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I phoned the Resolute Bay hamlet office. I talked to a woman who had difficulty understanding anything I asked. She managed to tell me that Resolute Bay had changed to "Eastern Time" the day before. I don't recall any elaboration on what this meant. That was all I got out of the call. I don't remember whether or not I tried to do a "time check". I was left with the impression that Resolute Bay was still stuck on UTC-5 (EST in winter and CDT in summer). However, due to the challenging nature of the phone call, I decided to seek out an alternate source of information. I found an e-mail address for somebody by the name of Stephanie Adams whose job was listed as "Inns North Support Officer for Arctic Co-operatives". I was under the impression that Stephanie lived and worked in Resolute Bay. Note: I don't think this was same Stephanie Adams that appeared in the center of a well known U.S. based magazine. I sent an e-mail to Stephanie on Nov 03/2008. Stephanie forwarded my e-mail to somebody by the name of Silvano Cendou; I have no information on who Silvano is. On Nov 05/2008, Silvano responded with this: 'Hi Stephanie Resolute Bay did not turn their clocks back on Sunday! They kept the same time as they had proir to the change. Hope this helps you Silvano' Stephanie forwarded Silvano's e-mail back to me. The phone calls and the e-mails all pointed to the permanent use of UTC-5 with a "time zone change" twice a year. On Nov 13/2008 I sent a post to this mailing list; I stated that Resolute Bay was still using Eastern Standard Time in winter and Central Daylight Time in summer. #---------------------------------------------------------- I did not contact anybody in Resolute Bay for the next two and a half years. #---------------------------------------------------------- On March 14/2011 I phoned the hamlet office again. I was told that Resolute Bay had been using Central Standard Time over the winter of 2010-2011 and that the clocks had therefore been moved one hour ahead on March 13/2011. The person I talked to was aware that Resolute Bay had previously experimented with Eastern Standard Time but he could not tell me when the practice had stopped. #---------------------------------------------------------- On March 17/2011 I searched the Web to find an e-mail address of somebody that might be able to tell me exactly when Resolute Bay went off Eastern Standard Time. I stumbled on the name "Aziz Kheraj". Aziz used to be the mayor of Resolute Bay and he apparently owns half the businesses including "South Camp Inn". This website has some info on Aziz: http://www.uphere.ca/node/493 I sent Aziz an e-mail asking when Resolute Bay had stopped using Eastern Standard Time. Aziz responded quickly with this: 'hi, The time was not changed for the 1 year only, the following year, the community went back to the old way of " spring ahead-fall behind" currently we are zulu plus 5 hrs and in the winter Zulu plus 6 hrs' This of course conflicted with everything I had ascertained in November 2008. I sent Aziz a copy of my 2008 e-mail exchange with Stephanie. Aziz responded with this: 'Hi, Stephanie lives in Winnipeg. I live here, You may want to check with the weather office in Resolute Bay or do a search on the weather through Env. Canada. web site' #-------------------------------------------------------------- If I had realized the Stephanie did not live in Resolute Bay I would never have contacted her. I now believe that all the information I obtained in November 2008 should be ignored. Assuming Aziz is correct, America/Resolute needs some changes. I think it would be best to delete the "Resolute" rule, and then change "America/Resolute" to look like this: Zone America/Resolute 0 - zzz 1947 Aug 31 # Resolute founded -6:00 NT_YK C%sT 2000 Oct 29 2:00 -5:00 - EST 2001 Apr 1 3:00 -6:00 Canada C%sT 2006 Oct 29 2:00 -5:00 - EST 2007 Mar 11 3:00 -6:00 Canada C%sT The comments in zone.tab should be reverted back to: "Central Time - Resolute, Nunavut" I apologize for reporting incorrect information in 2008. -chris

> Along those lines, thanks to Curtis Manwaring from this list for > alerting me to the observed time zone anomaly for the Vidal > California area... Thanks. The question I have is how did the cell phone company (Verizon) know what time it was in Vidal, CA? There are what look to be 2 cell phone towers, one at Vidal Junction behind the only gas station (and California produce checkpoint) and another just over a mile south of the junction between rte 62 and 95. The time changes from Arizona (Mountain) to Pacific when traveling north of Vidal toward the junction. They must have a database somewhere and it would be nice to get a copy of that for the Olson database. Hopefully they've kept records going back several years. Sincerely, Curtis Manwaring

ITU-R redefinition, UTC as a timezone?
by Steve Allen July 12, 2011

July 12, 2011

This list has mentioned that in 2012 January the Radiocommunications Assembly (RA) will probably vote on a revision of ITU-R TF.460, the document which defines the time scale used in radio broadcasts, and thus also in internet time services. For more details on the decade-long history of that effort see my web page http://www.ucolick.org/~sla/leapsecs/onlinebib.html As currently worded the draft revision would abandon leap seconds in the UTC time scale. Adoption of the draft revision requires a 70% supermajority vote of the delegates. In 1970 (the previous instance of significant change to broadcast time signals) the wording of the draft was modified during the assembly. I would like feedback from the members of the tz mail list on the pros and cons of the applicability of a possible modification of the broadcast time signals which preserves the traditional meaning of time-of-day while removing the leap seconds from the broadcasts. The modification uses the existing zoneinfo database and code. I have a description and test example of the modification here http://www.ucolick.org/~sla/leapsecs/right+gps.html This is aimed as an implementation which can be tested now. If the ITU-R were to rename the broadcast time scale at the same time as abandoning leap seconds then it might also serve posterity. -- Steve Allen <sla(a)ucolick.org> WGS-84 (GPS) UCO/Lick Observatory--ISB Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m

IERS Message No. 192: Questionnaire to survey opinion concerning a redefinition of UTC
by central_bureau＠iers.org July 12, 2011

July 12, 2011

************************************************************************ IERS Message No. 192 July 12, 2011 ************************************************************************ Questionnaire to survey opinion concerning a redefinition of UTC After years of discussions, a proposal to fundamentally redefine UTC will come to a conclusive vote in January 2012 at the ITU-R in Geneva. This proposal would halt the intercalary adjustments known as leap seconds that maintain UTC as a form of Universal Time. If the proposal is approved, UTC would not keep pace with Earth rotation and the value of DUT1 would become unconstrained. Therefore UTC would no longer be directly useful for various technical applications which rely on it being less than 1 second from UT1. Such applications would require a separate access to UT1, such as through the publication of DUT1 by other means. The objective of the survey is to find out the strength of opinion for maintaining or changing the present system.

Re: DST in Fiji
by Petr Machata July 8, 2011

July 8, 2011

Hi there, I'm wondering if anyone knows whether Fiji should enter the period of DST in 2011 again, and when that should be. Timeanddate.com seem to expect it starts at years to come. But the only reference I was able to find is this one: http://www.fiji.gov.fj/index.php?option=com_content&view=article&id=2608:da… And that seems only related to the DST period that occured in 2010/2011. In particular, in the following line: "Daylight Savings will be from October 24 to March 6, 2011" ... I don't think that "October 24" should be understod as October of 2011. (The zoneinfo project doesn't currenty assume the DST will start in 2011 an on.) Thanks, Petr Machata

TAI zone?
by David Magda July 5, 2011

July 5, 2011

[Not a subscriber, so please CC.] Hello, There's been some discussion of removing leap seconds from UTC, as some people need/want a more predictable and deterministic time scale. [1] Given that International Atomic Time [2] exists, there doesn't seem to be an easy way to reference it. Is there any reason why a TAI "time zone" ("TZ=TAI; export TZ") is not present for those that want to ignore leap seconds? I noticed that some Linux distributions have a "right/" directory [3] to deal with this in some way: > Two different versions are provided: > - The "posix" version is based on the Coordinated Universal Time (UTC). > - The "right" version is based on the International Atomic Time (TAI), > and it includes the leap seconds. [...] > > - TZDIR=/usr/share/zoneinfo/posix TZ=Europe/Paris on a system with > hardware clock set to UTC. > - TZDIR=/usr/share/zoneinfo/right TZ=Europe/Paris on a system with > hardware clock set to TAI.

Clocks worldwide are synchronized via Coordinated Universal Time (UTC), an atomic time scale recommended by the Radiocommunications Sector of the International Telecommunications Union (ITU-R). A proposal to fundamentally redefine UTC will come to a conclusive vote in January 2012 at the Radiocommunications Assembly of the ITU-R in Geneva. It would halt the intercalary adjustments known as leap seconds that maintain UTC as a form of Universal Time, and eliminate the requirement that time services transmit the varying residuals (DUT1) between Coordinated Universal Time and Universal Time of day. If the proposal is approved, UTC would not keep pace with Earth rotation and the value of DUT1 would become unconstrained. Adverse impacts from redefining UTC have not been extensively researched and documented. The implications extend from technical infrastructure to legal, historical, logistical, sociological and economic domains. Affected technologies may include (but are not limited to) applications in astronomy, astrodynamics and celestial mechanics, geodesy, ground-to-space satellite communications, navigation, remote sensing and space surveillance. This meeting will provide a venue for discussing and documenting the repercussions of changing UTC along with possible mitigation strategies.

DST in America/Metlakatla?
by Bill Seymour June 17, 2011

June 17, 2011

I apologize if this is old news that somehow blew by me. I don't think the zone America/Metlakatla in northamerica is quite right yet. I think the rule in the last line of the zone should be "-", not "US". I'm guessing that that was just a typo. FWIW, I've confirmed independently that Metlakatla observes UTC-8 year-round. My day job is with the U.S. Postal Service, and I work on a system that schedules transportation, so time zones are important to me. Confused by the "US" in America/Metlakatla, I called the 99926 post office; and the woman I spoke to said, "Right now, we're the same time as the rest of Alaska. Fall/winter, we're the same as Seattle." --Bill Seymour "If this were my employer's opinion, I wouldn't be allowed to post it." -- Norman Diamond

Hi, Was working on strftime() and came across some info. You may already have it but didn't see it in the current "g" files. >From 29 December 2011, Samoa will advance its daylight savings time from UTC-10 to UTC+14 (and its standard time from UTC-11 to UTC+13), essentially moving the international date line to the other side of the country. http://en.wikipedia.org/wiki/UTC%2B14:00 Might be worth a look?

Your parser won't directly handle the Europe file, as it follows the majority of your rules, but created a different exception, which should allow more latitude for your rules, while hopefully simplifying exceptions in the parser unit. The "%" in front of "LETTER/S" signals direct or literal replacement much like the "-" is to "RULES". The Europe file was also rearranged slightly to group regions together for analysis. Thanks again and hope these help. Steve

Russian Time Change

Could you tell me when will this be done? Second, this staying DST change is a bit confusing for me. Should it be that Russia will return to Russian Standard Time and will increase time zone offset by one ? But from the proposed change, the offset is not change. Am I missing something here?. Lastly, I have seen the term of UTC+2 and UTC+2+1. For UTC+2+1, is it referring to time zone offset plus 2 with DST forward by one? Your help is appreciated.

Can you add permatime.com to the twinsun link page
by Tim Diggins May 19, 2011

May 19, 2011

Hi there - I've been lurking on the list for a while. I don't contribute much as a I'm a (humbly grateful) user of tz information, rather than a provider. I mentioned our http://permatime.com site, a while back, but don't think I explicitly asked for it to go on the twinsun link page under "Web pages using recent versions of the tz database". Can it? http://permatime.com is a service for generating and viewing links that refer to a particular point in time and can be displayed in multiple timezones. It uses the ruby tzinfo gem, based on the Olson Tz database. kind regards Tim http://permatime.com http://teamportfolios.com/permatime Tim Diggins http://red56.co.uk http://tim.teamportfolios.com/

Hi I was building, am building, a parser of your files.

Hello, This is the first time I've done this so, first up, please excuse my ignorance. I have downloaded ftp://elsie.nci.nih.gov/pub/tzdata2011g.tar.gz and ftp://elsie.nci.nih.gov/pub/tzcode2011g.tar.gz Although I find the comments about the changes this year: # From Dan Abitol (2011-03-30): # ...Rules for Africa/Casablanca are the following (24h format) # The 3rd april 2011 at 00:00:00, [it] will be 3rd april 1:00:00 # The 31th july 2011 at 00:59:59, [it] will be 31th July

Fwd: Improvement request: Concordia Station timezone
by Aurelien Jarno May 8, 2011

May 8, 2011

Hi, Please find below a mail from Paolo Perfetti, asking to create a new timezone for the Concordia station in Antartica. It seems there are already a few stations in the antartica file, so I guess it's possible to add a new entry. What information would be needed for that? He is Cc:ed to this mail, so don't hesitate to ask him more details directly.

Summer Time in the Church of the Holy Sepulchre
by Sascha Wildner May 2, 2011

May 2, 2011

Hi list, I just came across a sentence in the German Wikipedia (in the http://de.wikipedia.org/wiki/Via_Dolorosa article): "Dieser Kreuzweg wird von den Franziskanern in einer täglich Prozession ab 15:00 Uhr, während der Sommerzeit um 16:00 Uhr (da die Sommerzeit in der Grabeskirche nicht gilt), gebetet." It roughly translates as: "This Way of the Cross is being prayed by the Franciscans in a daily procession starting at 15:00, 16:00 during Summer Time (because Summer Time isn't observed in the Church of the Holy Sepulchre)." Does anyone have more information on this ("Summer Time isn't observed in the Church of the Holy Sepulchre"). Was it ever discussed here? Does it affect the tz database? Best regards, Sascha -- http://yoyodyne.ath.cx

proposed time zone package changes (Egypt et al.)
by Arthur David Olson April 21, 2011

April 21, 2011

Here are proposed changes to the time zone package; the executive summary: Makefile change GCC_DEBUG_FLAGS rule for more warnings africa Egypt abandons DST in 2011 (and forward) (thanks to Alexander Krivenyshev) localtime.c recode increment_overflow and long_increment_overflow to eliminate gcc warnings (thanks to Paul Eggert) europe eliminate doubled words (thanks to Jim Meyering) southamerica eliminate doubled words (thanks to Jim Meyering) The "africa" changes do affect time stamps in Egypt in 2011 (and forward).

FW: Clocks in Novosibirsk in 1957
by Olson, Arthur David (NIH/NCI) [E] April 21, 2011

April 21, 2011

I'm forwarding this message from Mark Brader, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado ________________________________________ From: Mark Brader [msb(a)vex.net] Sent: Wednesday, April 20, 2011 7:49 PM To: Olson, Arthur David (NIH/NCI) [E] Subject: Clocks in Novosibirsk in 1957 Here is an item I found accidentally on page 16 of the (Toronto) Globe and Mail for April 25, 1957, while I was searching online for another topic. I thought the members of TZ might be interested in the Novosibirsk part and amused by the rest. Please forward to the list if you think appropriate. I am not on the list; replies should be directed accordingly. I have not gone to the library to locate the cited article in Maclean's (a Canadian newsmagazine). There may be small errors due to the scan not being fully legible as well as my own errors in typing. # Only an Hour Apart # Clocks in Novosibirsk # Comparatively Simple # # by MAGGIE GRANT # # In a recent issue of Maclean's Magazine, Blair Fraser mentions the # plight of citizens of Novosibirsk, Siberia, who for 38 years have # had the clocks at the east end of their city one hour faster than # those of the west end. # # This is due to a time boundary running smack through the middle # of the city, and Mr. Fraser dubs the Novosibirskites the "world's # most patient people" for putting up with this situation for so long. # # Now, I sympathize with Siberian citizens on almost every count, # but I cannot shed any tears over this one. Having a city's clocks # exactly one hour apart for 38 years sounds like an ideal arrangement # to me. I'm certain that a normally intelligent person would take # no more than a few days to catch on to the time differential, # and surely any dunce would know which end of the city was which. # # Therefore, a western Novosibirskite, caught in the eastern end # of town, would in all probability do little more than glance at # a clock before exclaiming: # # "Zlug' Krztoxni ghow'. Qwetevinoff da gmuy zlot pzis ud gvenn!" # Which translated means: "By Jove! A quarter to eight! I must # hurry if I am to be home for dinner at seven!" # # Compared to this simple situation, consider the trials to which # I am subjected by the timepieces under my roof. # # There is the grandfather clock in the hall, for instance, a family # heirloom and a charming thing to look upon. But the poor old dear # has never recovered from the shock of being moved from Mother's # house to mine, and simply cannot keep itself going. I have long # ago written it off as a deadhead, but Mother is a tenacious soul, # and every once in a while she hopefully sets the pendulum in motion. # If she would only warn me on these occasions, I would not be so # alarmed when it suddenly bongs out some totally irrelevant hour. # # The Empire clock on the mantel, on the other hand, has a # delightfully silvery voice. It keeps accurate time, too, but is # addicted to flipping its minute hand into the fireplace at frequent # intervals. These occurrences are apt to go unnoticed until the # time is urgently needed to set other clocks, when the cry goes up: # "The hand! The hand! It's off again!" and all activity ceases # in favor of ash-sifting. The offending member, once retrieved, # is dusted off and replaced on the dial at the time we presume to # be correct, but which seldom is. # # Another horological eccentric hangs on the kitchen wall, an electric # model in perky red and white to match the decor. Unfortunately it # got knocked down one day, and although we put it all together as # best we could, it has observed none of the laws of Greenwich since. # # You can look at that clock one minute and it will point to 12:10, # but three minutes later, glancing at it again, you will discover # that it has moved on to 4:30. Never once have I caught it in the # act of whizzing from point to point, and this I regret, because # I am sure it would be a challenging experience. # # The other electric timepiece is immobilized once a week by # Mrs. Swallow, the charlady, who favors its especial wall plug # above all others for vacuum cleaning activities. # # Further undependables about the place are two travelling clocks that # run for 18 and 15 hours respectively, and a wristwatch that is good # for only 11. Under these circumstances, I consider it rather unfair # of people to call me Laggy Maggie. After all, I do the very best # I can by going from room to room, jotting down the various times, # adding them up, and then striking an average. Although I admit the # system is far from perfect, it's the best I've been able to devise. # # I wonder if somebody in Novosibirsk can offer a better one? -- Mark Brader, Toronto "Don't be silly -- send it to Canada" msb(a)vex.net -- British postal worker

Did Irkutsk NOT switch from IRKT to KRAST?
by Tim Parenti April 19, 2011

April 19, 2011

I've been alerted to a couple reports that on 2011-03-22, the Russian government decided NOT to allow the Irkutsk Oblast to transition from IRKT (UTC+8) to KRAST (UTC+7+1) on 2011-03-27, and that instead Irkutsk transitioned to IRKST (UTC+8+1) under the existing Russian DST rules and plans to stay there for the time being like the rest of the country. The articles are in Russian, which I don't speak, but I've provided excerpted Google translations below. The reports follow: http://www.irk.ru/news/20110325/time/ (2011-03-25) Irkutsk region remains in its time zone March 27 residents of the Irkutsk region with the rest of the Russians set the clock forward one hour. Previously reported that the Angara will not translate clock to daylight saving time and thereby reduce the difference with Moscow, with 5:00 to 4. Irkutsk officials have prepared all necessary documents. However, an official decision on this has not been signed. In this case, the matter has not withdrawn completely, but only postponed indefinitely. http://gazetavremya.ru/day/16739-irkutskaya-oblast-poteryalas-vo-vremeni.ht… Irkutsk region is lost in time After that we asked for comments to the Legislative Assembly of Irkutsk region Yuri Faleichik, who confirmed this information and added that it is the most painless for our scheme to reduce the time difference with the capital from 5 to 4 hours. And suddenly, on Tuesday revealed that information on the transition to Krasnoyarsk time was premature! The same Jury Faleichik told our newspaper: - The decision to move the Irkutsk region in the time zone of the Krasnoyarsk Territory Government is not accepted. Our source in the regional government said that the decision "not to move to Krasnoyarsk time" was made in connection with the upcoming elections. -- Tim Parenti

Re: Samoa's plans to shift the Inetrnational Dateline
by Gwillim Law April 19, 2011

April 19, 2011

The International Date Line is not defined by any international law or treaty. It is an arbitrary line drawn by cartographers, separating lands in the Pacific Ocean whose standard time is later than UTC from those whose standard time is earlier than UTC. Therefore, if Samoa decides to shift its standard time from UTC-11 to UTC+13, the cartographers will simply redraw the line to the east of Samoa. The same thing happened in 1995, when Kiribati changed the date for its eastern island groups. The Line Islands and the Phoenix Islands had been observing a different date, one day earlier than the Gilbert Islands where most of the people of Kiribati lived. In 1995, the Line and Phoenix groups were shifted forward by one day. They didn't need the approval of any international agency. In response, new maps began appearing with a large displacement in the International Date Line, skirting all of Kiribati along the country's eastern limit. "... the term 'International Date Line' is thus in fact a misnomer. Its exact course was never defined by any international treaty, law or agreement." (http://www.phys.uu.nl/~vgent/idl/idl.htm) "The IDL drawn on the map on this page and all other maps is now and always has been an artificial construct of cartographers-the precise course of the line in international waters is arbitrary. No international organization nor any treaty between nations has fixed the "straight line" segments and their junctions. All nations unilaterally determine their standard time zones..." (http://en.wikipedia.org/wiki/International_Date_Line) I hope that addresses your question adequately. Yours, Gwillim Law ----- Original Message ----- From: Leilani Tuala Warren The Samoa law Reform Commission has been tasked with looking into how Samoa can shift the international dateline so that it is in the same time zone as NZ, Fiji and Tonga rather than USA. Can we please enter into some dialogue as to how this can be done on a global scale?

April 13, 2011

Here are some compiler warnings that it would probably be good to be rid of. The compiler is optimizing away intended overflow tests in some cases. Results of integer operations are officially undefined when overflow occurs, so the compiler is within its rights in making this kind of assumption. $ gcc -Wall -O3 -c *.c localtime.c: In function ‘timesub’: localtime.c:1541: warning: assuming signed overflow does not occur when assuming that (X + c) < X is always false localtime.c:1545: warning: assuming signed overflow does not occur when assuming that (X - c) > X is always false localtime.c: In function ‘T.144’: localtime.c:1727: warning: assuming signed overflow does not occur when assuming that (X + c) < X is always false localtime.c:1738: warning: assuming signed overflow does not occur when assuming that (X + c) < X is always false localtime.c:1748: warning: assuming signed overflow does not occur when assuming that (X + c) < X is always false localtime.c:1752: warning: assuming signed overflow does not occur when assuming that (X - c) > X is always false localtime.c:1768: warning: assuming signed overflow does not occur when assuming that (X - c) > X is always false zdump.c: In function ‘main’: zdump.c:442: warning: assuming signed overflow does not occur when assuming that (X - c) > X is always false $ gcc --version gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3 -- Andy Heninger

FW: last call for draft-lear-iana-timezone-database-03
by Eliot Lear April 11, 2011

April 11, 2011

Hi everyone, We need your help. We have made substantial progress in seeing to a permanent home for the TZ database and mailing list after Arthur David Olson's retirement. The announcement below indicates that the Internet Engineering Steering Group (IESG) is now asking for feedback on the proposal, which is for the function to be homed by the IANA (Internet Assigned Numbers Authority). The intent, again, is to document existing practice, and to establish a succession process. Now is the time for you to signify your agreement or disagreement with this proposal. Please send your comments to ietf(a)ietf.org, perhaps copying this mailing list. The IESG needs to hear from you as the most impacted community. Please do let them know what you think.

FW: Test cases for zoneinfo data
by Olson, Arthur David (NIH/NCI) [E] April 11, 2011

April 11, 2011

I'm forwarding this message from Christopher Hunt, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado -----Original Message----- From: Christopher Hunt [mailto:huntc@internode.on.net] Sent: Thursday, December 16, 2010 12:15 To: tz(a)lecserver.nci.nih.gov Subject: Test cases for zoneinfo data Hi there, I'm creating a set of Java classes that closely reflect the structure of the Zoneinfo database. My requirement is driven mostly by wanting to dynamically update Java TimeZone classes i.e. as opposed to compiling a zoneinfo data and re-starting my application. In addition I feel that the ICU and Sun classes do not accurately reflect Zoneinfo structures. I shall open-source this project once it gets to a working point. It'd be terribly helpful if I could get hold of some test cases, automated or otherwise, that verify correct time zone calculations. Would anyone out there have such things? Kind regards, Christopher

April 10, 2011

Hi there, Any further advice on this? I noticed it was down too and, while it doesn't effect the ftp site, it is a little disconcerting. After all, zoneinfo is incredibly important! Going forward, do you see that there could be a more appropriate place for the zoneinfo website and its corresponding ftp site to live (even if it is just from a DNS perspective)?

Zoneinfo TZ v1.0.0 is now available
by Christopher Hunt April 3, 2011

April 3, 2011

Hi there, I've now made my Java implementation of a Zoneinfo parser and java.util.TimeZone facade available as open source via The Codehaus. My implementation closely honours the domain model of Zoneinfo. My project can be found at: http://zoneinfo-tz.codehaus.org/ and a v1.0.0 has now been cut. I shall shortly push the v1.0.0 artifact to the Maven central repository. I was wondering if the Zoneinfo website could be updated to include a link to it under the "Other tz-based time zone software" heading, and possibly just underneath the Sun Java line. Thanks for the consideration! Kind regards, Christopher

Falkland Islands to not fall back this year
by Steffen Thorsen April 1, 2011

April 1, 2011

The Falkland Islands will not turn back clocks this winter, but stay on daylight saving time. One source: http://www.falklandnews.com/public/story.cfm?get=5914&source=3 We have gotten this confirmed by a clerk of the legislative assembly: Normally the clocks revert to Local Mean Time (UTC/GMT -4 hours) on the third Sunday of April at 0200hrs and advance to Summer Time (UTC/GMT -3 hours) on the first Sunday of September at 0200hrs. IMPORTANT NOTE: During 2011, on a trial basis, the Falkland Islands will not revert to local mean time, but clocks will remain on Summer time (UTC/GMT - 3 hours) throughout the whole of 2011. Any long term change to local time following the trial period will be notified. Best regards, Steffen Thorsen - timeanddate.com

Introduction
by Derick Rethans March 31, 2011

March 31, 2011

Hi! This is a message to test the list, and to mention that I'm the maintainer of PHP's Date/Time support. We're using our own bundled version of the Olson DB (with a few additions). Hopefully, soon, we'll implement the rules themselves and not only the transition times. cheers, Derick

update to proposed changes
by Arthur David Olson March 31, 2011

March 31, 2011

The proposed changes below incorporate the suggested change in translation of comments regarding Chilean DST, a reference to the English-language page regarding DST in Morocco, and a change so that DST in Morocco ends at midnight rather than 1:00. These changes are against the current ftp versions. I'll try to update the ftp versions on Friday. And...messages don't seem to be appearing on... http://blog.gmane.org/gmane.comp.time.tz ...but do seem to be appearing elsewhere. --ado diff -c old/africa new/africa *** old/africa Thu Dec 16 12:24:19 2010 --- new/africa Wed Mar 30 15:29:23 2011 *************** *** 1,5 **** # <pre> ! # @(#)africa 8.28 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)africa 8.30 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 712,717 **** --- 712,759 ---- # http://www.timeanddate.com/news/time/morocco-starts-dst-2010.html # </a> + # From Dan Abitol (2011-03-30): + # ...Rules for Africa/Casablanca are the following (24h format) + # The 3rd april 2011 at 00:00:00, [it] will be 3rd april 1:00:00 + # The 31th july 2011 at 00:59:59, [it] will be 31th July 00:00:00 + # ...Official links of change in morocco + # The change was broadcast on the FM Radio + # I ve called ANRT (telecom regulations in Morocco) at + # +212.537.71.84.00 + # <a href="http://www.anrt.net.ma/fr/"> + # http://www.anrt.net.ma/fr/ + # </a> + # They said that + # <a href="http://www.map.ma/fr/sections/accueil/l_heure_legale_au_ma/view"> + # http://www.map.ma/fr/sections/accueil/l_heure_legale_au_ma/view + # </a> + # is the official publication to look at. + # They said that the decision was already taken. + # + # More articles in the press + # <a href="http://www.yabiladi.com/articles/details/5058/secret-l-heure-d-ete-maroc-lev"> + # http://www.yabiladi.com/articles/details/5058/secret-l-heure-d-ete-maroc-lev + # </a> + # e.html + # <a href="http://www.lematin.ma/Actualite/Express/Article.asp?id=148923"> + # http://www.lematin.ma/Actualite/Express/Article.asp?id=148923 + # </a> + # <a href="http://www.lavieeco.com/actualite/Le-Maroc-passe-sur-GMT%2B1-a-partir-de-dim"> + # http://www.lavieeco.com/actualite/Le-Maroc-passe-sur-GMT%2B1-a-partir-de-dim + # anche-prochain-5538.html + # </a> + + # From Petr Machata (2011-03-30): + # They have it written in English here: + # <a href="http://www.map.ma/eng/sections/home/morocco_to_spring_fo/view"> + # http://www.map.ma/eng/sections/home/morocco_to_spring_fo/view + # </a> + # + # It says there that "Morocco will resume its standard time on July 31, + # 2011 at midnight."

I'm forwarding this message from Brian Garrett; Brian is on the mailing list. --ado -----Original Message----- From: Brian Garrett [mailto:mgy1912@cox.net] Sent: Wednesday, March 30, 2011 9:56 PM Subject: Re: DST new rules for 2011 in Africa/Casablanca timezone My spoken French is not all that fluent, but my written comprehension is good enough for this: Rabat- L'heure légale au Maroc sera avancée d'une heure à partir du samedi 2 avril 2011 à 24h00, indique une source responsable du ministère de la Modernisation des secteurs publics. Le retour à l'heure normale se fera à compter du dimanche 31 juillet 2011 à minuit. L'heure sera retardée de soixante minutes à 24h00 samedi 30 juillet 2011. Un projet de décret a été élaboré à cet égard et sera présenté lors de la prochaine réunion du conseil de gouvernement. Translation: "Rabat--The legal time in Morocco will be advanced one hour beginning Saturday, 2 April 2011 at 24:00, says a responsible source at the Mininstry of Public Sector Modernisation. The return to normal time will take place (literally: do itself) starting Sunday, 31 July 2011 at midnight. The time will be turned back sixty minutes at 24:00 [on] Saturday 30 July 2011. A draft of an official statement on this matter has been drawn up and will be presented at the time of the next government council meeting." So it seems that at midnight Saturday the 2nd (= 2011-04-03T00:00:00) it will become 2011-04-03T01:00:00, local time in Morocco. The "fall back" time is ambiguous, though. 24:00 on 30 July and midnight on 31 July are the same time, namely 2011-07-31T00:00:00. Assuming the clocks are changing Saturday night, is it 24:00 _after_ the time change, or before? It does not help that they included a picture of clocks changing at 2:00/3:00 in the article :(( Brian Garrett -------------------------------------------------- From: "Petr Machata" <pmachata(a)redhat.com> Sent: Wednesday, March 30, 2011 9:17 AM To: <tz(a)lecserver.nci.nih.gov> Subject: Re: DST new rules for 2011 in Africa/Casablanca timezone > "Olson, Arthur David (NIH/NCI) [E]" <olsona(a)dc37a.nci.nih.gov> writes: > >> I'm forwarding this message from Dan Abitol, who is not on the time zone >> mailing list.

Again changes in Chile...
by Horst H. von Brand March 28, 2011

March 28, 2011

It has just been decreed that the change will now be the first Saturday of May, returning to normal time on the second Saturday of October. See <http://www.horaoficial.cl/cambio.htm> (the text is confusing, as it says the change will take place as stated "or as the competent authorities indicate", but radio and other news are announcing the stated dates). Noise at the political level indicates that DST could be abolished for the future. Sorry, I'm not familiar enough with the rules to fix this properly. And there is little time left to fix this. -- Dr. Horst H. von Brand User #22616 counter.li.org Departamento de Informatica Fono: +56 32 2654431 Universidad Tecnica Federico Santa Maria +56 32 2654239 Casilla 110-V, Valparaiso, Chile 2340000 Fax: +56 32 2797513

Chile extends daylight saving time again
by Steffen Thorsen March 28, 2011

March 28, 2011

Chile will extend DST again, this time to (the end of) 2011-05-07. They will also start DST early, third Saturday in August, which probably means they will turn their clocks forward when the mainland enter Sunday, 2011-08-21.

What is time being called in Russia now?
by Olson, Arthur David (NIH/NCI) [E] March 28, 2011

March 28, 2011

Now that the clocks have sprung forward, can anyone with a presence in Russia report on whether they are calling current time "daylight" or "summer" or "standard"? Thanks for any light you can shed. (Remember that computer outputs are poor to use for this purpose; they're often based on the time zone database.) --ado

Chile changes the DST change AGAIN
by Glenn Eychaner March 28, 2011

March 28, 2011

The article: http://diario.elmercurio.com/2011/03/28/_portada/_portada/noticias/7565897A… In English: Chile's clocks will go back an hour this year on the 7th of May instead of this Saturday. They will go forward again the 3rd Saturday in August, just as before 1968. This is a pilot plan which will be reevaluated in 2012. Sigh.

Asia/Irkutsk split
by alexander.ray＠internode.on.net March 28, 2011

March 28, 2011

In the time zone change Russia took this March, Irkutsk Oblast began using Krasnoyarsk Time while Buryatia didn't, so a split of Asia/Irkutsk is in order, creating Asia/UlanUde (?). Additionally, the elves at Wikipedia have discovered that Tomsk Oblast didn't change to Omsk Time at the same time as Novosibirsk Oblast. http://en.wikipedia.org/wiki/Time_in_Russia#Tz_database Source (in Russian) http://newsru.com/russia/01may2002/clock.html
