by Paul Eggert 25 May '15

25 May '15

It's March Madness time for daylight-saving rule changes. Here's a proposed change to the tz database to keep up with the latest political development, which affects time stamps starting March 29: * Latvia and Lithuania will not observe DST, starting this year. Thanks to Andrei Ivanov for this info. =================================================================== RCS file: RCS/europe,v retrieving revision 2000.3 retrieving revision 2000.3.0.1 diff -pu -r2000.3 -r2000.3.0.1 --- europe 2000/03/04 15:31:08 2000.3 +++ europe 2000/03/08 17:48:59 2000.3.0.1 @@ -1135,6 +1135,12 @@ Link Europe/Rome Europe/San_Marino # 1997-01-21 on transition to Summer time ... established the same order of # daylight savings time settings as in the States of the European Union. +# From Andrei Ivanov (2000-03-06): +# This year Latvia will not switch to Daylight Savings Time (as specified in +# <a href="http://www.lv-laiks.lv/wwwraksti/2000/071072/vd4.htm"> +# The Regulations of the Cabinet of Ministers of the Rep. of Latvia of +# 29-Feb-2000 (#79)</a>, in Latvian for subscribers only). + # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Latvia 1989 1996 - Mar lastSun 2:00s 1:00 S Rule Latvia 1989 1996 - Sep lastSun 2:00s 0 - @@ -1151,7 +1157,8 @@ Zone Europe/Riga 1:36:24 - LMT 1880 3:00 Russia MSK/MSD 1989 Mar lastSun 2:00s 2:00 1:00 EEST 1989 Sep lastSun 2:00s 2:00 Latvia EE%sT 1997 Jan 21 - 2:00 EU EE%sT + 2:00 EU EE%sT 2000 Feb 29 + 2:00 - EET # Liechtenstein # Zone NAME GMTOFF RULES FORMAT [UNTIL] @@ -1178,6 +1185,11 @@ Zone Europe/Vaduz 0:38:04 - LMT 1894 Jun # motion to give up shifting to summer time in spring, as it was # already done by Estonia. +# From Andrei Ivanov (2000-03-06): +# I've heard that Ministers of three Baltic countries on their summit +# somewhere in February decided not to switch to summer time starting from +# this spring. + # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Europe/Vilnius 1:41:16 - LMT 1880 1:24:00 - WMT 1917 # Warsaw Mean Time @@ -1192,7 +1204,8 @@ Zone Europe/Vilnius 1:41:16 - LMT 1880 2:00 C-Eur EE%sT 1998 2:00 - EET 1998 Mar 29 1:00u 1:00 EU CE%sT 1999 Oct 31 1:00u - 2:00 EU EE%sT + 2:00 EU EE%sT 2000 Feb + 2:00 - EET # Luxembourg # Whitman disagrees with most of these dates in minor ways; go with Shanks.

FW: Updated Australian time zone names/strings
by Olson, Arthur David (NCI) 17 Apr '01

17 Apr '01

David Begley is not on the time zone mailing list; direct replies appropriately. --ado -----Original Message----- From: David J N Begley [mailto:d.begley@uws.edu.au] Sent: Thursday, March 22, 2001 3:40 AM To: Time Zone Database Subject: Updated Australian time zone names/strings To whom it may concern... Summary: I'd like to request the "EST/EST" time zone strings for Australian eastern standard and summer/daylight-savings time be changed to "AEST/AEDT", given that "EST/EST": - clashes with an existing U.S. time zone; - gives no indication of the difference between standard/d'light savings; - is unnecessarily confusing; - is incorrectly quoted from the time zone database as authoritative; and, - does not necessarily gel with "common practice" in Australia. Whilst it is arguable exactly what string/abbreviation should be used in the absence of formal standards, I present "common usage" examples below and argue that at the very least, the abbreviations for standard and daylight savings time should be *different*. Detail: Checking the tzdata2001a archive (and various UNIX systems), Australian eastern time zones (particularly "Australia/Sydney") use the time zone string "EST" for both standard and summer/daylight-savings time. Notionally, this is just a visual issue that doesn't really bring the IT industry to its knees if it's wrong since most decent systems work directly on the UTC offset instead. However, some systems use the time zone database as an "expert reference" from which to extrapolate incorrect information - it is this that triggered my submission to you. For example, the time zone database includes the following comment: # From John Mackin (1991-03-06): # We in Australia have _never_ referred to DST as `daylight' time. # It is called `summer' time. Now by a happy coincidence, `summer' # and `standard' happen to start with the same letter; hence, the # abbreviation does _not_ change... I can't speak for Mr Mackin's direct experience, but I can most certainly contest the assertion that, "We in Australia have _never_ referred to DST as `daylight' time" - certainly everyone I know (and myself, of course) have always used the term "daylight savings" rather than "summer time". I've used UNIX systems for years so to a certain degree I'm used to this "error" in the time zone database; however, now that people are using the database as an authoritative resource (despite the comments in the file to the contrary), I thought it only fair to request a correction (in the hope that those relying on the database will in turn correct their information). Mr Mackin continues: # The legislation does not actually define abbreviations, at least # in this State, but the abbreviation is just commonly taken to be the # initials of the phrase, and the legislation here uniformly uses # the phrase `summer time' and does not use the phrase `daylight # time'. Unfortunately Mr Mackin does not indicate to what State he refers, but in *this* State (New South Wales - NSW), the relevant legislation clearly uses both terms (summer time and daylight savings) interchangeably; for reference, see the Standard Time Act 1987 (NSW), which *predates* Mr Mackin's comment: "New South Wales Consolidated Acts - STANDARD TIME ACT 1987" http://www.austlii.edu.au/au/legis/nsw/consol_act/sta1987137/ Whilst the Act clearly defines "standard time" and "summer time", it also makes specific mention of "daylight saving": - the long title of the legislation is: "An Act relating to standard time and daylight saving in New South Wales." - part 3 of the Act, talking about summer time, is in fact entitled: "PART 3 - DAYLIGHT SAVING" For further evidence of the use of the term "daylight saving", see: "Time in New South Wales" (NSW Attorney General's Department) http://www.lawlink.nsw.gov.au/crd.nsf/pages/time1 "Daylight Saving in New South Wales" (NSW Department of Public Works and Services) http://dir.gis.nsw.gov.au/cgi-bin/genobject/document/other/daylightsaving/ti gGmZITWr0 "When does daylight savings start in Australia?" (National Standards Commission) http://www.nsc.gov.au/PAGES/Info/info_faq.html#Daylight Savings "Daylight Saving" (National Standards Commission) http://www.nsc.gov.au/PDF_WORD/Info/IL27.pdf Clearly, the assertion that Australia always uses the term "summer time" instead of "daylight time" or "daylight savings" (and therefore, the time zone abbreviations must be the same) is *incorrect*. The confusion arises because in Australia it is the States (not the Federal/national government) that legislate time changes during the summer months; whilst technically it is a federal responsibility under the constitution (as a measure related to commerce), the parliament has never really been able to pass legislation on the matter due to the fear that the States would see this as removing some of their legislative powers (see Hansard, Commonwealth House of Representatives, 1991). Subsequently, there is no standard name for time zones or summer clock shifts just "common use" (for various definitions of "common") that sometimes vary from State to State. In the media you will experience all manner of phrases used such as "Eastern Time", "Summer Time", "Sydney Time" and numerous other variants; for example, C&W Optus (a large telco) uses abbreviations such as "AEDST" when referring to Australian eastern daylight savings time. I suspect, apart from Mr Mackin's comments above, that the local use of the phrase "Eastern Standard Time" (which is clearly local in context) is what has led to the use of the ambiguous "EST" in the time zone database. More recently, however, the media is recognising the global context (rather than local) and starting to prefix time zone references with "Australian" (more on this below). As noted above, this confusing lack of standards, local phrases and personal experiences have found their way into the time zone database, into nearly every UNIX system (well...) and has now created even more confusion, especially as some people start to quote the time zone database as authoritative. For example: "Australian time zones and their naming variants account for fully one quarter of all time zones in the Postgres time zone lookup table." http://www.postgresql.org/users-lounge/docs/7.0/user/datetime-appendix.htm (Caused by wierd variants - many of which I must admit to never having seen in use - to the ambiguous "EST". Also note that they recognise "AEST".) More of a concern, is this: "4.5. The timezone string for Sydney/Australia is wrong since even when daylight saving time is in effect the timezone string is EST. "{UD} The problem for some timezones is that the local authorities decided to use the term 'summer time' instead of 'daylight saving time'. In this case the abbreviation character `S' is the same as the standard one. So, for Sydney we have Eastern Standard Time = EST Eastern Summer Time = EST Great! To get this bug fixed convince the authorities to change the laws and regulations of the country this effects. glibc behaves correctly." http://www.gnu.org/software/libc/FAQ.html This is clearly based on Mr Mackin's comment in the time zone database, and as I have demonstrated is wrong (in terms of the legislation and government use). Unfortunately, despite the evidence, the glibc authors simply point to the time zone database as authoritative and allow this error to continue. glibc is *not* behaving correctly, nor is the time zone database (but to correct glibc I need to get the time zone database updated). So.. by this time I hope I've demonstrated that it *is* legitimate (and correct) to use a different abbreviation for daylight savings/summer time; all that remains is to demonstrate why I've chosen "AEST" and "AEDT" to replace "EST" for standard and daylight savings time respectively. Well, ignoring my own use of these abbreviations, some "common use" includes: - Australian Broadcasting Corporation <http://www.abc.net.au/news/> - Browse the ABC News site and see the instances of "AEST" and "AEDT" (even "ACST" and "AWST" for central and western standard time) in reference to eastern standard or eastern summer time depending on whether that particular State observes daylight savings or not. - In particular, see the "Posted" timestamps at: <http://www.abc.net.au/news/state/nsw/default.htm> - The home page currently has a timestamp (towards page top-right) of: "This Bulletin: Thu, Mar 22 2001 4:15 PM AEDT". - Even at the bottom of the first news page is the explanation of "AEDT" (which may disappear this weekend when DST ends in NSW): "AEDT = Australian Eastern Daylight Time which is 11 hours ahead of UTC (Greenwich Mean Time)" - These pages also appear in a search of the Commonwealth Government's <http://www.fed.gov.au/> Web site. - Australian Department of Defence <http://www.defence.gov.au/> - See various media releases, for example, referring to times in either "AEST" or "AEDT", including: <http://www.defence.gov.au/media/1997/05797.html> <http://www.defence.gov.au/media/1997/01197.html> - National Library of Australia <http://www.nla.gov.au/> - Search their Web site for "AEST", references to contacting them give times in this time zone: <http://www.nla.gov.au/dss/libraries_os.html#express> - Australian Taxation Office (ATO) - http://www.ato.gov.au/content.asp?doc=/content/tax_reform/nat3402.htm - Australian Football League (AFL) - Fixture times: <http://www.afl.com.au/matches/season_111.htm> - Australian Cricket Board (ACB) - Live game coverage: <http://www-aus.cricket.org/link_to_database/NATIONAL/AUS/MATCHES/> - "The Australian" (and other Murdoch/News-owned newspapers) - Example: <http://australianit.news.com.au/common/storyPage/0,3811,902553%255E2184,00. html> - You have to "view source" to see the "Updated...AEST" - Visible at the very bottom, "All times AEDT" - Other (small sample) - NineMSN's News service <http://www.news.ninemsn.com.au/> (notice current time given in AEDT) - "...each fortnightly Sunday morning at 8am AEST/AEDT" http://news.ninemsn.com.au/smallbusiness/help/help9.asp - AAP IS/News, as viewed through <http://au.dailynews.yahoo.com/> (pick AAP-sourced articles and notice times in "AEDT" and "AEST") The examples go on and on. As you can see, it is not just government sites using the time zones "AEST" and "AEDT" in this manner. An argument could probably be mounted to have all the Australian time zones altered accordingly (probably along the lines used by the ABC and The Australian), but it's mainly the Australia/Sydney time zone that interests me at present. I hope this is sufficient information/examples for consideration, but would be happy to provide further info/examples if necessary. Thanks for your consideration (and sorry for this being so long); hope to hear your comments soon. Cheers.. dave

EU directive
by Joseph S. Myers 31 Mar '01

31 Mar '01

Since this doesn't seem to have been mentioned here yet: the latest Summer Time Directive (Directive 2000/84/EC of the European Parliament and of the Council of 19 January 2001 on summer-time arrangements) was published in the Official Journal of the European Communities on the 2nd of February, providing for dates of last Sunday in March to last Sunday in October on a permanent basis. No sign yet of an order being laid before Parliament to implement this directive in the UK (due to be done by 31 December). http://europa.eu.int/eur-lex/en/lif/dat/2000/en_300L0084.html 300L0084 Directive 2000/84/EC of the European Parliament and of the Council of 19 January 2001 on summer-time arrangements Official Journal L 031 , 02/02/2001 P. 0021 - 0022 Text: Directive 2000/84/EC of the European Parliament and of the Council of 19 January 2001 on summer-time arrangements THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION, Having regard to the Treaty establishing the European Community, and in particular Article 95 thereof, Having regard to the proposal from the Commission(1), Having regard to the opinion of the Economic and Social Committee(2), Acting in accordance with the procedure laid down in Article 251 of the Treaty(3), Whereas: (1) The eighth Directive, 97/44/EC, of the European Parliament and of the Council of 22 July 1997 on summer-time arrangements(4) introduced a common date and time in all Member States, for the beginning and end of summer time in 1998, 1999, 2000 and 2001. (2) Given that the Member States apply summer-time arrangements, it is important for the functioning of the internal market that a common date and time for the beginning and end of the summer-time period be fixed throughout the Community. (3) Since the summer-time period considered most appropriate by the Member States runs from the end of March to the end of October, it is appropriate that that period therefore be maintained. (4) The proper functioning of certain sectors, not only transport and communications, but also other sectors of industry, requires stable, long-term planning. Provisions concerning summer time should therefore be laid down for an unspecified period. Article 4 of Directive 97/44/EC provides, in that respect, that the European Parliament and the Council are to adopt, by 1 January 2001, the arrangements to apply from 2002 onwards. (5) For reasons of clarity and accuracy of information, a timetable for the implementation of the summer-time period for the following five years should be published every five years. (6) Implementation of this Directive should, moreover, be monitored by means of a report, to be presented by the Commission to the European Parliament, the Council and the Economic and Social Committee, on the impact of these provisions in all of the areas concerned. That report should be based on the information made available to the Commission by the Member States in sufficient time to enable the report to be presented at the specified time. (7) Given that the complete harmonisation of the timetable for the summer-time period with a view to facilitating transport and communications cannot be sufficiently achieved by the Member States and can therefore be better achieved at Community level, the Community may take measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty. This Directive does not go beyond what is necessary to achieve those objectives. (8) For geographical reasons, the common summer-time arrangements should not apply to the overseas territories of the Member States, HAVE ADOPTED THIS DIRECTIVE: Article 1 For the purposes of this Directive "summer-time period" shall mean the period of the year during which clocks are put forward by 60 minutes compared with the rest of the year. Article 2 From 2002 onwards, the summer-time period shall begin, in every Member State, at 1.00 a.m., Greenwich Mean Time, on the last Sunday in March. Article 3 From 2002 onwards, the summer-time period shall end, in every Member State, at 1.00 a.m., Greenwich Mean Time, on the last Sunday in October. Article 4 The Commission shall publish a communication in the Official Journal of the European Communities(5), for the first time on the occasion of the publication of this Directive, and every five years thereafter, containing the timetable showing the dates on which the summer-time period will begin and end for the following five years. Article 5 The Commission shall report to the European Parliament, the Council and the Economic and Social Committee on the impact of the provisions of this Directive on the sectors concerned by 31 December 2007 at the latest. That report shall be drawn up on the basis of the information made available to the Commission by each Member State by 30 April 2007 at the latest. The Commission shall, if necessary and following the conclusions of the report, make appropriate proposals. Article 6 This Directive shall not apply to the overseas territories of the Member States. Article 7 Member States shall bring into force the laws, regulations and administrative provisions necessary to comply with this Directive by 31 December 2001 at the latest. They shall forthwith inform the Commission thereof. When Member States adopt those measures, they shall contain a reference to this Directive or be accompanied by such a reference on the occasion of their official publication. Member States shall determine how such reference is to be made. Article 8 This Directive shall enter into force on the day of its publication in the Official Journal of the European Communities. Article 9 This Directive is addressed to the Member States. Done at Brussels, 19 January 2001. For the European Parliament The President N. Fontaine For the Council The President B. Ringholm (1) OJ C 337, 28.11.2000, p. 136. (2) Opinion delivered on 29 November 2000 (not yet published in the Official Journal). (3) Opinion of the European Parliament of 12 December 2000 (not yet published in the Official Journal) and Council Decision of 20 December 2000. (4) OJ L 206, 1.8.1997, p. 62.

Solaris patched to avoid "ROC" time zone name for political reasons
by Paul Eggert 29 Mar '01

29 Mar '01

On Tuesday, Sun released patch 111099-01 for Solaris 8 (x86) entitled "ROC timezone should be avoided for political reasons". This patch creates the zone Asia/Taipei (which is normally not installed in Solaris) and then creates ROC as a link. The patch does not include the source code (in this case, the 'asia' file) so unfortunately I can't report Sun's comments (if any) about the situation. (If Sun were selling to North Korea, I guess "ROK" would be next to go. :-)

IERS Message No. 7
by central_bureau＠iers.org 27 Mar '01

27 Mar '01

*************************************************************************** IERS Message No. 7 March 27, 2001 *************************************************************************** ITRF Report 4 on local ties Report on local tie problems in colocation sites as result from ITRF2000 Analysis Zuheir Altamimi IERS ITRS Product Center Institut Geographique National, France Date: March 22, 2001 The importance of local ties in space geodetic colocation sites is no longer to be demonstrated. Their impact on the ITRF solutions is very critical since they represent the key element of ITRF combination. Based on ITRF2000 residual analysis, the current situation of local ties is summarized in the following two tables: Table 1: Missing Local Ties: Sites where local ties between some or all points are missing (information is not available at IERS ITRS Product Center). Table 2: Dubious local ties: Sites where local tie estimates differ from Space Geodesy estimates. The current local ties collected by the ITRS-PC since more than 10 years come from heterogeneous sources and do not always contain quality (precision) information, necessary for rigorous ITRF combination. These local ties are used in ITRF combinations as observations with proper variances. In case where these variances are not available, they are computed using a geodetic formula given in ITRF publications. Note that a dubious local tie is declared as such if its ITRF2000 post fit residuaul is larger than or equal to 1 cm. This threshold of 1 cm is the minimum requirement for a global frame aimed to be good to at least 1 ppb level (6 mm over the Earth's surface). Therefore the ITRF2000 residual analysis is a tool to assess their quality or their level of agreement with Space Geodesy estimates. Dubious local ties are due to at least one of the following reasons: - They are imprecise - They are in error - Space Geodesy estimate is imprecise - Space Geodesy estimate is in error Each one of these two tables is sorted in two categories, according to their importance for ITRF: ***: Highly Important Sites, given their geographic location and/or quality of their geodetic instruments. These critical sites are mostly those where local ties between points observed by at least two different techniques are not available (Table 1), respectively dubious (Table 2). This is the case for example of: - Wuhan (China) where the local tie between the SLR and GPS points is not available. - Fairbanks (ALASKA) where the local tie between the VLBI and GPS points is dubious. * : Very Important Sites, given the quality of their geodetic instruments. These sites are those where SOME local ties are not available (resp. dubious). This is the case for example of: - Tromso (Norway) where the new GPS point is not connected to VLBI, SLR, DORIS or the old GPS points. - Wettzell (Germany) where the local tie connecting the SLR point 8834 (S018) is dubious. In order to remedy this situation, it is recommended to initiate efforts starting with Highly important sites. A useful information (per-site residual summary and plots) highlighting the quality of local ties in ITRF2000 colocation sites is available on the web at: http://lareg.ensg.ign.fr/ITRF/ITRF2000/valsit.html Table 1: Missing Local Ties Sites where local ties between some or all points are missing Missing tie per DOMES Site Name Country Imp Technique (Point) ----- ---------------- -------- --- -------------------------------- Highly Important Sites 10317 NY-ALESUND NORWAY *** VLBI(S003 7331) 12309 MENDELEEVO RUSSIA *** SLR(S001 1870), GPS(M002 MDVO) 12329 YUZHNO-SAKHALINS RUSSIA *** GPS(M003 YSSK), DORIS(S001 SAKA) 12337 SIMEIS UKRAINE *** SLR(M001 7561), SLR(S003 1873) SLR(S006 1893), VLBI(S008 7332) 21602 WUHAN CHINA *** SLR(S003 7236), GPS(M001 WUHN) 21605 SHANGHAI CHINA *** GPS(M002 SHAO), VLBI(S008 7226) 21609 KUNMING CHINA *** GPS(M001 KUNM), SLR(S002 7820) 21612 URUMQI CHINA *** GPS(M001 URUM), VLBI(S001 7330) 21701 KASHIMA JAPAN *** SLR(M002 7335), VLBI(S001 1856) VLBI(S004 1857), VLBI(S006 7334) 21704 KOGANEI JAPAN *** SLR(M001 7328), SLR(S002 7308) S002(S004 7327) 21729 USUDA JAPAN *** VLBI(S001 7246), GPS(S007 USUD) 23903 SUWN-SHI S.
