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.

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.

I guess I object strongly to including legislative proposals into the tzdata files. If we introduce a new file and a new timezone everytime some government official makes some silly comment about time, the whole edifice will collapse under the weight of that garbage. While the tzdata file is not an official publication it is regarded as pretty authoritiative by most people using computers in the world. It should therefore strive to be accurate and authoritative, and not get bogged down with irrelevancies, and political commentary or jokes (which is the only thing I can imagine that the Pacific-New timezone to be). > > As to jokes and idiocy: there used to be an obscure bit of word play in > an strftime.c comment; > it was eliminated in version 7.40.-) Never saw it. I am not above jokes and wordplay but not when it extends to introducing new time zones in at least semi-authoritative publications. Are we going to get an Okeefenokie time zone because someone likes Pogo-- or a US/BUSH timezone (constantly set to midnight) as political commentary on the last president? That an ill-considered proposal popped up in Congress 20 years ago but was never passed should not be memorialised by a new time zone in tzdata. My response was triggered when a Suse user said his distro assigned Pacific-New to him. Having never seen it before (Mandriva wisely does not have it), I looked at the tzdata file and found it. Please please remove it. > > --ado > -- William G.

Why is there not a Asia/Beijing timezone?

The standard time in China is Beijing time. Why is there no Beijing timezone in your database? Microsoft Windows has a Beijing time zone.
