Europe/Taunton?
by Zefram Jan. 20, 2012

Jan. 20, 2012

http://www.bbc.co.uk/news/uk-politics-16611058 Mr Rees-Mogg has tabled an amendment to the proposed legislation suggesting the "the county of Somerset as defined by the Lieutenants Act shall revert to the customary time used prior to the Great Western Railway time established in 1840". Jacob Ress-Mogg MP is quite a character, and it's a very conservative character. He has that special skill of being nostalgic not only for a time before he was born, but for a time before his great-great-grandparents were born. His amendment is extremely unlikely to be adopted, but its prospective consequences bear some thinking about. He'd make Somerset the only place on Earth where the timezone is not a multiple of five minutes offset from UT. In fact, it wouldn't even be an exact multiple of *one* minute, if implemented in full. And since the pre-1840 custom was for every town to have its own time, we wouldn't just need Europe/Taunton, but potentially several other new zones for different Somerset towns. If any form of the Rees-Mogg amendment were to be adopted, it would more likely be a single timezone for the whole county, an integral number of minutes offset from UT. Taunton (largest town in, and capital of, Somerset) is at some 3.1 degrees west, suggesting a 12 minute offset. -zefram

Re: [tz] Russia may scrap time change

A year ago when Russia scrapped the seasonal switch and decided to advance an hour "permanently", I said to myself "finally someone in the Russian Govt "gets it"".

Russia may scrap time change
by Alexander Krivenyshev Jan. 20, 2012

Jan. 20, 2012

Russian Prime Minister Vladimir Putin promised to convey to President Dmitry Medvedev suggestions from Russian football fans about the cancellation of the transition to winter time. During an informal conversation with the head of government organizations, football fans raised the issue that the cancellation of the transition to winter creates uncomfortable conditions. In particular, it leaves less time for sleep. If, for example, a football match is broadcast rather late in European time, due to the time difference it makes getting up early for work difficult.

Moldova in zone.tab
by Zefram Jan. 20, 2012

Jan. 20, 2012

Now that Moldova has split into two timezones, the zones need descriptions in zone.tab. However, tzdata2011m only gives a description for the new Europe/Tiraspol, leaving the old Europe/Chisinau with no description. This violates the format of zone.tab. (Which makes my automatic repackaging for CPAN protest.) Following examples such as Chile and Greenland, I believe the appropriate description for Europe/Chisinau is "most locations". -zefram

leap seconds reprieved until 2015

Jan. 19, 2012

The ITU couldn't reach consensus on leap seconds, and has deferred the issue until 2015. UTC continues with leap seconds for the time being. http://www.bbc.co.uk/news/science-environment-16625614 -zefram

Posix time zone question
by Donald MacQueen Jan. 17, 2012

Jan. 17, 2012

Hi all, I am adding time zone support to our multi-platform application and there are still a few things I cannot figure out. 1) What is the difference between America/Detroit and posix/America/Detroit? The test cases I have written return what looks like the same DST record for a given date no matter which one I use. Under what circumstances would I use posix/America/Detroit? 2) Where is the format of the tz source filesdescribed? Specifically what do SAVE and Letter/S mean below? I am also interested in what the Link format is. # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Nic 1979 1980 - Mar Sun>=16 0:00 1:00 D Rule Nic 1979 1980 - Jun Mon>=23 0:00 0 S 3) AIX machines use their own wacky format such at TZ=EST5EDT. Is there any decent mapping to real names? I have googled my brains out on this and searched the comp.time.tz archives on gmane with no luck. Thanks in advance, Donald

Tokelau crossing date line
by Gwillim Law Jan. 17, 2012

Jan. 17, 2012

A correspondent informed me that Tokelau, like Samoa, will be skipping December 31 this year, thereby changing its time zone from UTC-10 to UTC+14. When I tried to verify this statement, I found a confirming article in Time magazine online (http://www.time.com/time/world/article/0,8599,2103243,00.html) The Wikipedia article on Tokelau also mentions the change. To the best of my knowledge, this hasn't been reported to the tz list yet. Yours, Gwillim Law

Timezone abbreviations
by Alain Petit Jan. 5, 2012

Jan. 5, 2012

[As I was using an incorrect email, I am resending. Apologies if duplicates were issued] Hi I am looking at the following timezone definition # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Metlakatla 15:13:42 - LMT 1867 Oct 18 -8:46:18 - LMT 1900 Aug 20 12:00 -8:00 - PST 1942 -8:00 US P%sT 1946 -8:00 - PST 1969 -8:00 US P%sT 1983 Oct 30 2:00 -8:00 US MeST I am trying to make sense of the MeST [the format]. I think PST means "Pacific Standard Time", and P%sT becomes PST or PDT according to the US rule in effect [and making it Pacific Standard Time or Pacific Daylight Time]. However I cannot figure out what MeST would be, apart from Metlakatla Standard Time ? [I found MEST - Middle European Standard Time, but Metlakatla is not in Europe] Searching for Metlakatla [google] always refers it as AKST [Alaska Standard Time]. So 2 questions a) What would MeST mean? [and why no '%s' for it?] b) Where can I find the meaning of these abbreviations [as I will probably find others that will confuse me in the future] Thanks -Alain

On line 213 of the europe file of the tzdata2011n.tar.gz archive there is a URL: http://student.cusu.cam.ac.uk/~jsm28/british-time/ This appears to no longer exist, I believe the correct URL is now: http://www.polyomino.org.uk/british-time/ I'm not sure if this is the correct process to report a bug, please let me know.
