by Paul Eggert May 25, 2015

May 25, 2015

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.

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/

I don't know if this simply means that Tomskaya oblast' changed timezone since 2001, which is a possibility, that would then require a new timezone.
