Nov. 7, 2011

Hello, Europe/Samara has the follow zone.tab definition since 2010g (no offset listed) RU +5312+05009 Europe/Samara Moscow - Samara, Udmurtia It used to be RU +5312+05009 Europe/Samara Moscow+01 - Samara, Udmurtia Samara changed to Moscow but all the other regions are listed with an offset even if +00 (Volgograd, Moscow) while Samara is not. I can not tell by searching the mail archive if the change this way was intentional or not? Thanks - Manpreet

tzdata2011n.tar.gz

Nov. 2, 2011

The file ftp://munnari.oz.au/pub/tzdata2011n.tar.gz ...is now available; this reflects changes circulated last week, and weekend, on the time zone mailing list, and summarised here. There are three changes of note - most urgently, Cuba (America/Havana) has extended summer time by two weeks, now to end on Nov 13, rather than the (already past) Oct 30. Second, the Pridnestrovian Moldavian Republic (Europe/Tiraspol) decided not to split from the rest of Moldova after all, and consequently that zone has been removed (again) and reinstated in the "backward" file as a link to Europe/Chisinau. And third, the end date for Fiji's summer time this summer was moved forward from the earlier planned Feb 26, to Jan 22. Apart from that, Moldova (MD) returns to a single entry in zone.tab (and the incorrect syntax that was in the 2011m version of that file is so fixed - it woudl have been fixed in a different way had this change not happened - that's the "missing" sccs version id). Once again, no signatures, but hash digests using several different algorithms are appended to this message so you can verify the file that you fetch. These were generated using the pkgtools/digest program from NetBSD's pkgsrc. kre MD5 (tzdata2011n.tar.gz) = 20dbfb28efa008ddbf6dd34601ea40fa RMD160 (tzdata2011n.tar.gz) = 4a2a06ada05aca1ea99767caa1b23c6fcb88bcd3 SHA1 (tzdata2011n.tar.gz) = 5435fae9844dc89f9d418aa956e161e23d1babdf SHA512 (tzdata2011n.tar.gz) = 2081fa44f00ace6539ecc1296f454fb96bb4afa61114ffbc58f46f82ef8ba2cfa22d7e48456a293502433dccca6d921db8f70d6c6e18a074996cfeb74534d2df TIGER (tzdata2011n.tar.gz) = 28b009b1e0e7126c2430270efd1aae89237be7c00b3ad2a5 WHIRLPOOL (tzdata2011n.tar.gz) = e7004894829c63baef91fd5fbc14b77a7fbd92ae2a6e001f279c8b1169bd5be009ae07af336ddaca148eadeba3383896b247a19c9e72d894e80ad60fc896f3f3

Rule Russia incorrect
by Konstantin Kivi Nov. 2, 2011

Nov. 2, 2011

Time Zone Data v. 2011m (Released 24 October 2011) file contains a line ---------------------------------------------------------------------------------- Rule Russia 1993 2010 - Mar lastSun 2:00s 1:00 S ---------------------------------------------------------------------------------- which I believe means that last change to summer time was in 2010. This is incorrect, because this (2011) year we actually have changed time on last Sunday of March (by moving clock forward) I believe that for historical purposes the rule must looks as follows ---------------------------------------------------------------------------------- Rule Russia 1993 2011 - Mar lastSun 2:00s 1:00 S ---------------------------------------------------------------------------------- On the other hand Rule --------------------------------------------------------------------------------------- Rule Russia 1996 2010 - Oct lastSun 2:00s 0 - ----------------------------------------------------------------------------------------- is correct, because Russia stopped using Daylight Savings Time switching because of a federal law "On calculation of time" signed by President Dmitry Medvedev on June 9, 2011 -- Sincerely yours, Konstantin Kivi <konst(a)sirena2000.ru> IT Director, Comtech-N JSC Moscow, Russia, +7-495-941-60-02

Re: [tz] Sydney, Australia (and other places) DST indication (or lack thereof)

I appreciate the info. Several of the links given in the Australasia file are broken, which, of course, makes it impossible to review the referenced source, but I can see that this is a muddled subject. The only suggestion I would make is that if the "S" in EST is referring to both "standard" and "summer", then the FORMAT should be EST/EST...and maybe a "# (S)tandard/(S)ummer" comment added. At the very least it clearly indicates the decision that's been made for daylight saving time representation. As to what it should be...I'll leave that to the Australians (oh wait...isn't that the problem to begin with?) ;) On Mon Oct 31 12:55:06 2011 "Bill Tiede" <billt(a)chaossoftware.com> wrote: > For WorldTimeServer.com at least, we used two government sources for our time zone abbreviations for Australia: > > 1.

Sydney, Australia (and other places) DST indication (or lack thereof)
by Willy＠willylorenzo.com Oct. 30, 2011

Oct. 30, 2011

I'm testing my zone conversion process and I thought I could just check the conversion with the Internet. So I get local time for Sydney, Australia, and then check my result with internet searches by searching for "time in Sydney Australia." Bing returns Current time in Sydney, New South Wales, Australia It is currently 11:31:34 AM on 10/30/2011 (AUS Eastern Daylight Time) Google returns 11:31am Sunday (EST) - Time in Sydney NSW, Australia Time oriented sites... timeanddate.com returns Sunday, October 30, 2011 at 11:31:34 AM EDT worldtimeserver.com returns 11:31 AM Sunday, October 30, 2011 Eastern Daylight Time (EDT) +1100 UTC (I selected both of those because they're referenced in the australasia data.) The two websites returned "EDT", and Bing implies "EDT" with its "Eastern Daylight Time." I thought I had a bug, but review of the tz database clearly states otherwise...it's "EST". Google was the only one to get it right (according to the tz database, that is.) So I'm wondering if anyone knows if there is some unwritten accepted practice of referring to Australian daylight saving time as EDT in colloquial speech, even though that labeling doesn't actually exist. Any thoughts on the subject are appreciated.

Proposed time zone package changes (Fiji, Pridnestrovie Moldova)
by Robert Elz Oct. 30, 2011

Oct. 30, 2011

Here are proposed changes to the time zone package. Just two updates this time. The executive summary europe Pridnestrovian Moldavian Republic (Europe/Tiraspol) has not followed much of Russia, and will not retain summer time - rather reverting to standard time along with western Europe, and Ukraine, on Oct 30, as it was earlier scheduelled to do. This removes the Europe/Tiraspol zone (again) as the variation never actually happened... (and returns the entry in the "backward" file). australasia Fiji has altered the end date for summer time this summer, moving it from February to January. I am by no means confident it won't shift again, but this does appear to be the current plan. To go with those, the backward file has Europe/Tiraspol returned to it (linking it to Europe/Chisinau) and zone.tab returns to a single entry for Moldova (MD). I plan to release these next Monday (October 31) - this means that anyone using Europe/Tiraspol and the tzdata2011m data set will get incorrect timestamps on Oct 30 (after 03:00 or whatever) and Oct 31 (until after the update), but the easy solution is to simply use Europe/Chisinau in all parts of Moldova. The missing sccs id version number in zone.tab is/was the unreleased version with the corrected syntax for the Moldovan entries when it was split. kre --- australasia 2011/10/15 03:21:32 1.4 +++ australasia 2011/10/24 16:58:31 @@ -1,5 +1,5 @@ # <pre> -# @(#)australasia 8.28 +# @(#)australasia 8.29 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. @@ -308,6 +308,20 @@ # advance at 2am to 3am on October 23, 2011 and one hour back at 3am to # 2am on February 26 next year. +# From Ken Rylander (2011-10-24) +# Another change to the Fiji DST end date.

The file ftp://munnari.oz.au/pub/tzdata2011m.tar.gz ...is now available; this reflects changes circulated last week on the time zone mailing list, with minor corrections as pointed out on the list. In particular, the typos in comments in the data (2011-11-17 should have been 2011-10-17 as Alan Barrett noted, and spelling of Tiraspol that Tim Parenti noted) have been fixed, and the change for Ukraine has been made in all 4 Ukrainian zones, rather than just Kiev (again, thanks to Tim Parenti, and also Denys Gavrysh) In addition, I added Europe/Tiraspol to zone.tab. This time, all the files have new version numbers... (including the files otherwise unchanged in 2011m that were changed in 2011l but didn't get new version numbers there...) Still no proper signatures, so once again, crypto digest values using several algorithms (from the NetBSD pkgsrc digest program) are appended, and can be used to verify that the file you fetched is the same as the one I generated. kre MD5 (tzdata2011m.tar.gz) = 6dc4455b62c951dcf367a239ca249e69 RMD160 (tzdata2011m.tar.gz) = e5b56e7d1be05a43fe3acd64522831475c2c531e SHA1 (tzdata2011m.tar.gz) = e6374cd41c5bffd7ade27c365c4bdc5213bb9d85 SHA512 (tzdata2011m.tar.gz) = 4d37ad2f4f2d89f7dadc70a5abb8bc946ff4668501723aea5f8a33ac0aa2b97df907753ae02a1b8d55e80d03cf4c22fcaac5e403a9a3b853514431213441e963 TIGER (tzdata2011m.tar.gz) = cff43577a2aa395b1057dce91ea0f9a10bf282c466fe421e WHIRLPOOL (tzdata2011m.tar.gz) = 33c5a59121de3499e1c07beb353c77ac6ecb33ff96fc397985811194e133f83743effd3e015ea0640e8d701ac42505b6c48250f33cd800e54744367f9a5603df
