by Paul Eggert March 9, 2014

March 9, 2014

The 2014a release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Changes affecting near-future time stamps Turkey begins DST on 2014-03-31, not 03-30. (Thanks to Faruk Pasin for the heads-up, and to Tim Parenti for simplifying the update.) Changes affecting past time stamps Fiji ended DST on 2014-01-19 at 02:00, not the previously-scheduled 03:00. (Thanks to Steffen Thorsen.) Ukraine switched from Moscow to Eastern European time on 1990-07-01 (not 1992-01-01), and observed DST during the entire next winter. (Thanks to Vladimir in Moscow via Alois Treindl.) In 1988 Israel observed DST from 04-10 to 09-04, not 04-09 to 09-03. (Thanks to Avigdor Finkelstein.) Changes affecting code An uninitialized-storage bug in 'localtime' has been fixed. (Thanks to Logan Chien.) Changes affecting the build procedure The settings for 'make check_web' now default to Ubuntu 13.10.

No Virgin Islands Data
by Hank W. March 8, 2014

March 8, 2014

The data for the Virgin Islands, both British & US, is missing. I checked an old dataset (2012j) and found them at the end of the northamerica file. They have since been replaced by a note saying 'see southamerica', but they're not in the southamerica file, either. Hank W., Austin, Texas, USA

Possible error in Europe/Kiev for 1991 - 1992
by Alois Treindl March 8, 2014

March 8, 2014

In western and Ukrainian astrology circles, there is on ongoing dispute about which timezone was in force in Kiev/Ukraine on the date the parliament decided about its independence, on 24 August 1991. Mostly, a timezone of GMT +3h is considered correct. This is in conflict with what TZ database states for that date. TZ database holds: # Most of Ukraine since 1970 has been like Kiev. Zone Europe/Kiev 2:02:04 - LMT 1880 2:02:04 - KMT 1924 May 2 # KievMTime 2:00 - EET 1930 Jun 21 3:00 - MSK 1941 Sep 20 1:00 C-Eur CE%sT 1943 Nov 6 3:00 Russia MSK/MSD 1990 3:00 - MSK 1990 Jul 1 2:00 2:00 - EET 1992 2:00 E-Eur EE%sT 1995 2:00 EU EE%sT Which makes reference to these DST rules #DST rules for Russia after WW2 Rule Russia 1981 1984 - Apr 1 0:00 1:00 S Rule Russia 1981 1983 - Oct 1 0:00 0 - Rule Russia 1984 1991 - Sep lastSun 2:00s 0 - Rule Russia 1985 1991 - Mar lastSun 2:00s 1:00 S Rule Russia 1992 only - Mar lastSat 23:00 1:00 S Rule Russia 1992 only - Sep lastSat 23:00 0 - Rule Russia 1993 2010 - Mar lastSun 2:00s 1:00 S Rule Russia 1993 1995 - Sep lastSun 2:00s 0 - Rule Russia 1996 2010 - Oct lastSun 2:00s 0 - #Modern EU rules Rule EU 1981 max - Mar lastSun 1:00u 1:00 S Rule EU 1996 max - Oct lastSun 1:00u 0 - # E-Eur differs from EU only in that E-Eur switches at midnight local time.

Via my US colleage David Cochrane, I received copies from a Moscow fellow, first name Vladimir, who reported several government documents, refering to Ukrainia timezones. Vladimir writes: --- quote Good news that now we have more documents online in Ukrainian language as well as Google translator. > why this decree states to go off DST when DST was not observed in Kiev in 1991. I did a research in laws and now we have an answer. Unfortunately, we should change a little our DST tables for Kiev and Ukraine. First in Ukraine they changed Time zone from UTC+3 to UTC+2 with DST: 03 25 1990 02:00 -03.00 1 Time Zone 3 with DST 07 01 1990 02:00 -02.00 1 Time Zone 2 with DST * Ukrainian Government's Resolution of 18.06.1990, No. 134. http://search.ligazakon.ua/l_doc2.nsf/link1/T001500.html They did not end DST in September, 1990 (according to the law, "summer time" was still in action): 09 30 1990 03:00 -02.00 1 Time Zone 2 with DST * Ukrainian Government's Resolution of 21.09.1990, No. 272. http://search.ligazakon.ua/l_doc2.nsf/link1/KP900272.html Again no change in March, 1991 ("summer time" in action): 03 31 1991 02:00 -02.00 1 Time Zone 2 with DST DST ended in September 1991 ("summer time" ended): 09 29 1991 03:00 -02.00 0 Time Zone 2, no DST * Ukrainian Government's Resolution of 25.09.1991, No. 225. http://www.uazakon.com/documents/date_21/pg_iwgdoc.htm This is an answer. Since 1992 they had normal DST procedure: 03 29 1992 02:00 -02.00 1 DST started 09 27 1992 03:00 -02.00 0 DST ended * Ukrainian Government's Resolution of 20.03.1992, No. 139. http://www.uazakon.com/documents/date_8u/pg_grcasa.htm ------ end quote I (Alois) interpret him like this: - On 1 Jan 1990, Kiev was on GMT + 3h (I call this 3he, 3 hours east). - on 25 March 1990, at 02:00 am, it went to DST, i.e. to 4he - on 1 July 1990, at 2:00 am, it shifted the standard time, kept the DST, moving effectively from 4he to 3he - no change on 30 Sept 1990, the kept DST, i.e. stayed on 3he (Russia ended DST on that data) - no change on 31 March 1991, Kiev stayed on 3he (Russia began DST on that data) - on 29 Sept 1991, at 03:00 am, Kiev ended DST, went to 2he - on 29 March 1992, 2:00 am, Kiev started DST, went to 3he - on 27 Sept 1992, 2:00 am, Kiev ended DST, went to 2he I have used Google translation to get the content of the links Vladimir provides: A) http://search.ligazakon.ua/l_doc2.nsf/link1/T001500.html " Set on 1 July 1990 in the Ukrainian SSR, the second time zone with the addition of one hour." This page says that Ukraine adopted 2he as standard time on 1 July 1990. One could interpret this that it talks about the timezone being 2he plus one hour. But I do not think it does. I think it means: Standard time moved to 2he, the clock was shifted west by one hour, i.e. one hour was added in the course of transition. (from h3e to h2e, if DST was not in force, or from h4e to h3e, if DST was in force). The statement does not confirm whether DST was in force or not at that data. B) http://search.ligazakon.ua/l_doc2.nsf/link1/KP900272.html states that on 30 Sept 1990, Ukraine did not turn clocks back, but continues to use DST. This implies that DST was indeed in force, at that time. C) http://www.uazakon.com/documents/date_21/pg_iwgdoc.htm states that on 29 September 1991, DST was ended and clocks set back by one hour. My conclusion is: TZ database missed the onset of DST in March 1990, and in consequence, missed its end in September 1991. The goverment document C) clearly states that DST ended in Ukraine on 29 Sept 1991, a date when TZ database says that DTS was not in force. I propose this correction of Europe/Kiev Zone Europe/Kiev 2:02:04 - LMT 1880 2:02:04 - KMT 1924 May 2 # KievMTime 2:00 - EET 1930 Jun 21 3:00 - MSK 1941 Sep 20 1:00 C-Eur CE%sT 1943 Nov 6 3:00 Russia MSK/MSD 1990 Jul 1 2:00 2:00 1:00 EET 1991 Sep 29 3:00 2:00 E-Eur EE%sT 1995 2:00 EU EE%sT

Wrong entry for Israel tz information
by AvigdorFin March 8, 2014

March 8, 2014

Greetings, It seems we found an error in Israel DST transition for the year 1988. Please check if I'm right and correct me it I'm wrong. This is the current information for the year, the transition has happened according to this on Friday night, changing to Saturday. $ zdump -v Israel | grep 1988 Israel Fri Apr 8 21:59:59 1988 UTC = Fri Apr 8 23:59:59 1988 IST isdst=0 gmtoff=7200 Israel Fri Apr 8 22:00:00 1988 UTC = Sat Apr 9 01:00:00 1988 IDT isdst=1 gmtoff=10800 Israel Fri Sep 2 20:59:59 1988 UTC = Fri Sep 2 23:59:59 1988 IDT isdst=1 gmtoff=10800 Israel Fri Sep 2 21:00:00 1988 UTC = Fri Sep 2 23:00:00 1988 IST isdst=0 gmtoff=7200 I check the Parliament ( Knesset ) records and there it's stated that the transition should take place on Saturday night, when the Sabbath ends and changes to Sunday. The definition in the source file is as follows: Rule Zion 1988 only - Apr 9 0:00 1:00 D Rule Zion 1988 only - Sep 3 0:00 0 S Which result with the times above. When changing the source to be: Rule Zion 1988 only - Apr 10 0:00 1:00 D Rule Zion 1988 only - Sep 4 0:00 0 S And compiling it with zic we get $ zdump -v Israel | grep 1988 Israel Sat Apr 9 21:59:59 1988 UTC = Sat Apr 9 23:59:59 1988 IST isdst=0 gmtoff=7200 Israel Sat Apr 9 22:00:00 1988 UTC = Sun Apr 10 01:00:00 1988 IDT isdst=1 gmtoff=10800 Israel Sat Sep 3 20:59:59 1988 UTC = Sat Sep 3 23:59:59 1988 IDT isdst=1 gmtoff=10800 Israel Sat Sep 3 21:00:00 1988 UTC = Sat Sep 3 23:00:00 1988 IST isdst=0 gmtoff=7200 And the transition is as decided by the parliament on Saturday night toward Sunday. I also added the following lines to the source file Link Asia/Jerusalem Israel Link Asia/Jerusalem IST-2IDT Please check me out and if I'm right, correct the next release of the tzdata file. I don't know how many people and organizations are still interested in data from 1988, but the record should be set right.

West Virginia broadcasters 1946 DST proposal
by Garrett Wollman March 8, 2014

March 8, 2014

Quoting from /Broadcasting * Telecasting/ of March 18, 1946: In a move believed to be unprecedented in radio, the newly-formed West Virginia Broadcasting Assn., comprising all stations in the state, will adopt daylight savings time form April 28 through Sept. 29 -- although West Virginia clocks will remain on standard time throughout that period. The time change was unanimously voted by the broadcasters at a meeting held in Charleston March 9. Representatives of all of the state's 14 stations agreed to the resolution. On March 12, all stations included the resolution in all newscasts. Under the plan, radio clocks will be changed to conform to network clocks [ed: the networks observed New York City time, which had DST in 1946] when time change occurs. This means that, unless the West Virginia legislature takes action to the contrary during a special session to be held in two weeks, West Virginians will have two time schedules -- that decreed by the state an that observed by radio. Time Announcements Participating stations will give time-announcements by the radio clock; they will make no rate adjustments, since their proposition is based on the assumption that West Virginia timekeepers are out of step with radio -- not vice versa. The article goes on to quote the full text of the resolution. -GAWollman

I think the fact that they could choose to call their resulting UTC-4 time zone "EDT" rather than "AST" probably wouldn't be in violation of the Uniform Time Act (but I'm not a lawyer either). That said, the federal Department of Transportation (which apparently has jurisdiction over such things) hasn't allowed Maine to move to Atlantic Time, so the odds that they'd allow Tennessee to do so seem rather low. (If Maine does ever manage to move its time zone, naming its zone identifier is going to be an interesting challenge for the TZDB -- since "America/Portland" is rather unfortunately ambiguous...) -- Jonathan Lennox lennox(a)cs.columbia.edu

timezone 2014 : Turkey delays DST start by one day
by Semih Sakiz Feb. 27, 2014

Feb. 27, 2014

Hello, According to Turkish government decision, there will be one-day delay in the start of DST. DST start time will be "2014 Monday, 31 March" instead of "2014 Sunday, 30 March" on Turkey. Is there a plan to update the time zone database for this change ? The latest timezone data on the URL "http://www.iana.org/time-zones" contains Time Zone Data v. 2013i and does not include the latest change in TURKEY.

Chile Time Change

That much notice would be a blessing. In years before 2013, the changes were made with as little as 5 days notice (notice Monday for a change in the date scheduled for the following Saturday). And as I said before, we have a goverment change on March 11, so all bets are off. -G.

Re: [tz] Chile to end DST earlier this year?
by Glenn Eychaner Feb. 18, 2014

Feb. 18, 2014

Nothing official has been announced at: http://www.horaoficial.cl/cambio_hora.html A quick search of newspapers for 'horario de invierno' also turns up nothing. However, keep in mind that Chile is in the midst of a government change; the inauguration of the new government is 11 March, and IIRC if the old government does nothing, the time change reverts to the old rule (March 8). I have no idea what to do about this. I knew making the new rule permanent would cause trouble. -G.

posix timestamp compatibility library for systems using right timestamp
by Marek Behun Feb. 12, 2014

Feb. 12, 2014

Hello, I have written a small POSIX timestamp compatibility library for glibc/linux systems which use right timestamp on system clock (and also a 'right/' timezone). By executing a program with LD_PRELOAD=/path/to/time2posix.so environment variable the program can still use a 'posix/' timezone and display system time correctly (system calls for getting/setting system time are patched byt time2posix.so). I wrote this library primarily for synchronizing time from NTP servers that use UTC. This way, when using for example ntpdate to synchronize from such a server, ntpdate doesn't have to be patched to synchronize to right timestamp (instead of posix). The library could also be used on programs that cannot use 'right/' timezone (for example PostgreSQL can't handle leap seconds and therefore won't accept a 'right/' timezone in configuration). For that though more system call patches need to be implemented. The sources can be found at https://github.com/elkablo/time2posix I would like to know if I should continue developing this library or if there are other ways of synchronizing to right timestamp correctly, or if right timestamp and consequently right timezones aren't used at all. Marek Behun

Glibc 2.19 adds support for version 3 tz format
by Paul Eggert Feb. 12, 2014

Feb. 12, 2014

The GNU C Library version 2.19, released February 8, adds support for version-3 format tz binary files. I thought I'd give this list a heads-up, in case other C-library maintainers are lurking and want to keep up with the Joneses. As you may recall, version 3 is a minor extension to the binary format, which adds support for some less-common timekeeping practices. So far, the only tz-database timestamps affected by this change are time stamps after the year 2037 in America/Godthab with tz data 2013e or later. These time stamps cannot be described by a POSIX TZ string, so version 3 uses the quasi-POSIX string 'WGT3WGST,M3.5.0/-2,M10.5.0/-1'. The glibc 2.19 announcement is at <https://sourceware.org/ml/libc-alpha/2014-02/msg00224.html>. More details about this change can be found at <https://sourceware.org/bugzilla/show_bug.cgi?id=15968>.
