completed timezone history of Germany
by Alois Treindl Aug. 30, 2011

Aug. 30, 2011

I have compiled a complete timezone history of Germany. It defines 10 additional zones for parts of Germany which had a timezone history different from Europe/Berlin Two of these zones refer to areas belonging to Poland since 1945. The processing of the zone file with zic requires that zic is patched with the 'follow rule' patch I had submitted for review on 25 August.

Shouldn't Kemerovo oblast' use OMST/OMSST timezone abbreviation?
by Petr Machata Aug. 29, 2011

Aug. 29, 2011

... given the time offset it could be either that, or NOVT that tzdata currently have. But Wikipedia lists Kemerovo under Omsk Time: http://en.wikipedia.org/wiki/Kemerovo_Oblast http://en.wikipedia.org/wiki/Omsk_Time In Russian: http://ru.wikipedia.org/wiki/%D0%9D%D0%BE%D0%B2%D0%BE%D0%BA%D1%83%D0%B7%D0%… http://www.lenta.ru/news/2009/09/23/belt/ Thanks, Petr Machata

The files... ftp://elsie.nci.nih.gov/pub/tzcode2011i.tar.gz ...and... ftp://elsie.nci.nih.gov/pub/tzdata2011i.tar.gz ...are now available; these reflect the changes circulated in the last two weeks on the time zone mailing list. It's one of the two times of year when we can expect frequent updates as countries change their rules; folks who want to avoid version churn may want to wait on updating. --ado

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/

3 Russian regions may change time zones on October 30, 2011
by Alexander Krivenyshev Aug. 22, 2011

Aug. 22, 2011

According to a government proposal published a few weeks ago on the Ministry of Industry and Trade of the Russian Federation Web site, 3 Russian regions may change time zones this autumn: Vladivostok (Primorsky region) – Move from MSK+7 to MSK +6 Sakha (Yakutia) – 3 current time zones collapsed into a single zone MSK+6 Irkutsk region – Move from MSK+5 to MSK +4 This document confirms that Moscow will use UTC+4 year round and all other regions except those listed above will keep current Summer time year round. Below are a few translated citations from original Russian government proposal: DRAFT DECISION OF THE GOVERNMENT OF Russian Federation “On the composition of the territories that make up each time zone, and the procedure of calculation of time within time zones, and the Repeal of certain resolutions of the Government of the Russian Federation on August 8, 2011” On October 30, 2011, at 02:00 local time the following new time calculations will be applied: Irkutsk region will use the 5th Russian time zone (MSK +4) Republic of Sakha (Yakutia) will use the 7th Russian time zone (MSK +6) Primorsky Krai (Vladivostok) will use the 7th Russian time zone (MSK +6) This draft proposal was signed by Russian Prime Minister Vladimir Putin. The original draft proposal was posted and is currently unavailable to view from the official government Web site. However, there is ongoing Russian media coverage and Worldtimezone.com was able to save the original posting. It can be viewed at the following link (use Google translation from Russian): http://www.worldtimezone.com/dst_news/dst_news_russia33.html Worldtimezone.com will keep you posted as new developments become available.

Re: China time zone
by An Yang Aug. 18, 2011

Dear Arthur, Thanks a lot. At first, let me show you some data: Population of Beijing in 2011 is 22,634,722, data from http://www.trueknowledge.com/q/population_of_beijing_in_2011 And population of Shanghai in 2011 is 22,447,529, data from http://www.trueknowledge.com/q/population_of_shanghai_in_2011 And of cause, you can check the population of Beijing and Shanghai in 1996, Beijing is 2,069,722, and Shanghai is 1,188,721. If your data source is http://www.world-gazetteer.com/wg.php?x=1263073253&men=gcis&lng=en&des=game… and http://www.citypopulation.de/world/Agglomerations.html What I can say, the data is wrong absolutely. The following is the data from the China Gov (Chinese only): http://www.shanghai.gov.cn/shanghai/node2314/node2319/node12344/u26ai25463.… http://www.bjstats.gov.cn/rkpc_6/pcsj/201105/t20110506_201580.htm All of these data is different, what should we trust? Let me try to explain it, frankly say, it's difficult to count the exact population of a city which have more than 20,000,000, especially in China. The population data from government, it just include the people who have the locale ID ( hukou ), do not include people without locale ID (hukou). So maybe 20-30% people lost, I think the data from http://www.trueknowledge.com is more accurate, which reflect the real number of people who live in the city. My conclusion is both Beijing and Shanghai are big city in China, and have almost the similar populations. According to the rule: Among locations with similar populations, pick the best-known location, e.g. prefer `Rome' to `Milan'. I think the best-known location is Beijing, no matter from Chinese view or from the foreigner's view. I have read all the messages about Beijing Time in ftp://elsie.nci.nih.gov/pub/tzarchive.gz, and notice that all the voice from China is the same, Beijing should represent China. So trust the people who live there and use Beijing time everyday maybe the best choice.
