Washington Post DST coverage
by Olson, Arthur David (NIH/NCI) April 3, 2003

April 3, 2003

The 2003-04-02 Washington Post's "KidsPost" page (C15) features the story "Well, It's About Time: With Daylight Saving, You Gain an Hour of Fun in the Sun." Franklin's place, the reason for non-year-round DST, and the reason it's "Daylight Saving" rather than "Daylight Savings" are all covered. A pointer to www.time.gov is provided. --ado

Daylight Savings Time in Israel (2003-2004)

On Tue, 11 Mar 2003, Rives McDow wrote: > Do you have any additional information about the daylight savings > changes in Israel for 2003? Minister of Interior Poraz has announced that he will respect the law passed in July 2000 (proposed at the time jointly by himself and then-MK David Azulai [Shas]) fixing the dates for 2000-2004. Hence, the dates for 2003 and 2004 remain unchanged: Year Start End ---- ----- --- 2003 Mar. 28 Oct. 3 2004 Apr. 7 Sep. 22 Where the start/end takes place at 1 AM old time (i.e. 1 a.m. IST => 2 a.m. IDT and 1 a.m. IDT => midnight IST). Timezone files for Israel can be found at: ftp://ftp.cs.huji.ac.il/pub/tz/israel/ As far as 2005 and beyond, no dates have been set. However, the minister has mentioned that he wishes to propose to move Israel's timezone in 2005 from GMT+2 to GMT+3 and upon that have DST during the summer months (i.e. GMT+4). However, no legislation in this direction is expected until the latter part of 2004 which is a long time off in terms of Israeli politics. ___________________________________________________________________________ Ephraim Silverberg, CSE System Group, Phone number: 972-2-6585521 Hebrew University, Jerusalem, Israel.

Iran daylight saving time correction
by Roozbeh Pournader March 16, 2003

March 16, 2003

Iran's daylight saving time is one day off. This is an English translation of what I just found (originally in Persian). The Gregorian dates in brackets are mine: -------------------------------------------------------------------------- Official Newspaper No. 13548-1370/6/25 [1991-09-16] No. 16760/T233 H 1370/6/10 [1991-09-01] The Rule About Change of the Official Time of the Country The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14], based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13] of the Country's Organization for Official and Employment Affairs, and referring to the law for equating the working hours of workers and officers in the whole country dated 1359/4/23 [1980-07-14], and for synchronizing the official times of the country, agreed that: The official time of the country will should move forward one hour at the 24[:00] hours of the first day of Farvardin and should return to its previous state at the 24[:00] hours of the 30th day of Shahrivar. First Deputy to the President - Hassan Habibi --------------------------------------------------------------------------- This affects all the tz data starting from 1992. >From personal experience, that agrees with what has been followed for at least the last 5 years. Before that, for a few years, the date used was the first Thursday night of Farvardin and the last Thursday night of Shahrivar, but I can't give exact dates. I'm searching for evidence of the exact dates of each year in the newspaper archives. But in the meanwhile, it'd be great to update the database with the attached patch. Iran will be in daylight saving in just a week, and current tz data is off one day. The new data is guaranteed to be correct from about 1998 until the end (2037). I have also changed the abbreivations to what is considered correct here in Iran, IRST for regular time and IRDT for daylight saving time. roozbeh

proposed tz changes for Lithuania, Tonga, Pakistan, Rothera, etc.
by Paul Eggert March 14, 2003

March 14, 2003

Spring is coming, so it must be time for a tz update. The patch enclosed below proposes the following changes. Lithuania is perhaps the most urgent case, as it changes its DST rules in a couple of weeks or so. Changes in the tz data proper: * Lithuania (Europe/Riga) will observe EU-style daylight-saving in 2003. Thanks to Klaus Marten for forwarding this info. * Tonga (Pacific/Tongatapu) stopped observing DST in January 2002. Thanks to Pulu 'Anau for this info. * Pakistan (Asia/Karachi) ends DST at the end of the first Saturday in October, not on October 15. Also, add 1 minute to the transition times, so they actually occur at 00:01 the next day. Thanks to Rives McDow for this info. * A new zone Antarctica/Rothera for Rothera Station, Antarctica. * Use the BEV for historical daylight-saving transitions for Europe/Vienna, applying the following corrections: Change 1918-06-16 to 1918-09-16. Change 1945-11-18 to 1945-04-12. Add transitions 1980-04-06 00:00 and 1980-09-28 00:00. Thanks to Janko Stamenovic for pointing out the BEV. * The PTB has come round to Shanks's opinions about double-daylight saving time for Europe/Berlin in 1945, so switch to Shanks. This changes the transition times from 05-31 03:00 to 05-24 02:00 and from 09-23 03:00 to 09-24 03:00. Thanks to Joerg Schilling for prompting me to look into this. * For Arizona/Phoenix, correct the date of the 1944 transition from 03-17 to 04-01. This correction comes from the Arizona State Library, Archives and Public Records. * The New Zealand Dept of Internal Affairs says that standard time was introduced in New Zealand on 1868-11-02; change to this date from Shanks's presumably-vaguer 1868-01-01. Changes in the auxiliary tables: * Yugoslavia has changed its name to Serbia and Montenegro. This does not affect the substance of the TZ tables, but it does change some commentary and a label in zone.tab. The ISO 3166 maintenance agency plans to determine a suitable country code, but this process has not been done yet, so we'll continue to use YU for the country code. Changes in commentary: * Thanks to Igor Karpov, a comment now records the official document number for daylight-saving in Ukraine. * Add a comment noting that our historic data for Chile disagrees with that of Chile's Hydrographic and Oceanographic Service, but we haven't had time to resolve the discrepancies. * Add more details in the comments about current US time zone boundaries. * It was Robert St John, not Bob Trout, who first reported the United States' transition from War Time to Peace Time on 1945-08-14. Changes in the tz-link.htm web page: * Put national histories of time zones in their own section. * Add URLs for Cygwin, RDF-based time zone representation, XCal, Sosigenes, Java, Python, Keim's new binary time zone file reader, Law's time zone concepts web page, and Google's index. * Remove URLs to obsolete web sites Timezone Converter (killed by changes to Perl), iCS (now Sun ONE). * Update URLs for IRIX, UnixWare. =================================================================== RCS file: RCS/antarctica,v retrieving revision 2001.3 retrieving revision 2001.3.0.1 diff -pu -r2001.3 -r2001.3.0.1 --- antarctica 2001/06/05 17:48:22 2001.3 +++ antarctica 2003/03/14 04:28:08 2001.3.0.1 @@ -255,6 +255,13 @@ Zone Antarctica/Vostok 0 - zzz 1957 Dec # Halley is on a moving ice shelf and is periodically relocated # so that it is never more than 10km from its nominal location. # Rothera, Adelaide Island, -6734-6808, since 1976-12-01 +# +# From Paul Eggert (2002-10-22) +# <http://webexhibits.org/daylightsaving/g.html> says Rothera is -03 +all year. # +# Zone NAME GMTOFF RULES FORMAT [UNTIL] +Zone Antarctica/Rothera 0 - zzz 1976 Dec 1 + -3:00 - ROTT # Rothera time # Uruguay - year round base # Artigas, King George Island, -621104-0585107 =================================================================== RCS file: RCS/asia,v retrieving revision 2002.4 retrieving revision 2002.4.0.1 diff -pu -r2002.4 -r2002.4.0.1 --- asia 2002/10/15 16:59:28 2002.4 +++ asia 2003/03/14 04:28:08 2002.4.0.1 @@ -748,7 +748,7 @@ Zone Asia/Jerusalem 2:20:56 - LMT 1880 # bill have until July 24 to pass. # # (2002-07-25): -# Thanks go to Yitschak Goldberg from E&M for bringing this (Hebrew) article +# Thanks go to Yitschak Goldberg from E&M for bringing this (Hebrew) +article # to my attention: # # http://www.ynet.co.il/articles/0,7340,L-2019315,00.html @@ -878,7 +878,7 @@ Zone Asia/Amman 2:23:44 - LMT 1931 # - Kazakhstan did not observe DST in 1991. # - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00. # - Oral switched from +5:00 to +4:00 in spring 1989. -# +# # # Zone NAME GMTOFF RULES FORMAT [UNTIL] # @@ -1154,9 +1154,13 @@ Zone Asia/Muscat 3:54:20 - LMT 1920 # and Sunday of April" phrase, if taken literally, means that the # transition takes place at 00:00 on the first Sunday on or after 04-02. +# From Paul Eggert (2003-02-09): +# DAWN <http://www.dawn.com/2002/10/06/top13.htm> reported on +2002-10-05 # that 2002 DST ended that day at midnight.

East Timor - Leste?
by Jesper Nørgaard March 9, 2003

March 9, 2003

I have noticed that some sources insist that there was a name change of East Timor to (the more portuguese correct) Timor Leste or Timor-Leste. Even official sources are not consistant in the naming, but I have noted that two important sources http://www.imf.org/external/country/index.htm and http://unstats.un.org/unsd/methods/m49/m49alpha.htm http://unstats.un.org/unsd/methods/m49/m49chang.htm are consistently using Timor-Leste. I presume that this is also where the recent East Timor (or Timor-Leste) abbreviations TLS (ISO 3-letter country code) and TL (ISO 2-letter country code) are derived from. Should we make a name change?

RE: FW: Error: end of DST Vienna 1918 is not in Jun
by Janko Stamenovic March 3, 2003

March 3, 2003

As far as I understand, the text means the following (my German is not perfect): "1945 daylight saving ended without particular decree, because of the end of the war. That transaction was given by the entrance of the occupation forces and occurred therefore in different parts of the country on different times, for example in Vienna apparently on 2. April 1945." I though that maybe it can be understood that it doesn't mean only that the daylight saving ended then, but that the occupation forces brought "their time", which was different in different parts of the country, since there were different troops? That is, that every Army had its own time rules? The other problem is that borders between the Armies certainly changed through the time. On http://www.magwien.gv.at/english/history/vhisaf.htm we can find about Vienna: "The political context was no less complicated, the Allied Occupation Forces refusing to accept the Nazis' territorial expansion. The bottom line was that those districts which had existed until 1938 were divided into four Allied zones and the inner-city district was administered by all four powers, as the so-called "Inter-allied Zone". Districts 22 - 26, namely the 97 Lower Austrian communities which had been merged with Vienna in October 1938, were considered to form part of Lower Austria and, hence, came under Soviet control." Therefore I deliberately pointed only to error in 1918, since it seems too hard point to solve without more information. Btw, BEV is Austrian "Federal Office of Metrology and Surveying". http://www.bev.gv.at so I guess their "?" really means that it's difficult to set some reasonable time. But something has to be set. There's one more difference between their info and zoneinfo, since one transition happens by them on 1946-10-07 (Monday) although 1946-10-06 as it is in zoneinfo looks better since it's Sunday (like the previous April transition, although it appears that they really almost always moved the clocks on Mondays (I don't know why) before and during WWII).

Pulu 'Anau has been added to the time zone mailing list at Pulu's request. This message arrived before Pulu's addition to the list. --ado -----Original Message----- From: Pulu 'Anau [mailto:pulu@infotech.afe.to] Sent: Tuesday, November 05, 2002 4:43 PM To: tz(a)lecserver.nci.nih.gov Subject: Tonga Daylight Savings Time ENDS... Hi, I'm a system administrator in a country that thinks it's funny to constantly play around with the time. To keep the story short, Tonga decided to create daylight savings time to get a jump on everyone for the new millenium. The law was for 3 years, supposedly to get renewed. It wasn't. Unfortunately, a good number of the systems I maintain (Debian Linux and OpenBSD) would like to believe the government here is reasonable and doesn't play around with stuff like this. Ha! Anyway, when they implemented daylight savings it took me a few hours to find the zone files and recompile them, and I don't think the changes were officially reflected (at least in Debian) for about a year. I don't really know where else to report this, but considering the vast amount of history that's already available in the data files, I hope this mailing list will work. I've modified the australasia file from the data file as below. I'm not a zic expert so I hope it's appropriate. It fixed the issue here, anyway. Also, in the compiled file that was pre-existing on this system (Debian 3.0), the file for Tongatapu had a bunch of junk in it, basically a help file for vi and some other binary data after the zoneinfo... I don't know if it's a debian thing or not, I'm not near the openbsd machines to take a look at them... Just FYI... If this file is going to explode on me at some later date, I'd really appreciate if someone could write back and let me know. Some of my customers rely on this information to do some dialup internet/mail stuff, and explaining they ought to complain to the government doesn't work because most of them are the government.
