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: Tonga Daylight Savings Time ENDS...
by Olson, Arthur David (NIH/NCI) Feb. 21, 2003

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.
