Russia May Discontinue DST in 2009- new draft proposal introduced.
by Alexander Krivenyshev July 26, 2008

July 26, 2008

A draft proposal of a new federal law to regulate time calculation within the territory of the Russian Federation has been offered by Sergei Mironov, a member of the Federal Council. Proposed at the legislative level, the draft seeks to determine the order of time calculation, under which the territory of the Russian Federation, during the entire calendar year is set to Standard Time plus 1 hour (current Decree time), without any additional time change (eliminating Daylight Saving Time/Summer Time). If approved this would take effect January 1, 2009. A current draft in Russian is available at the following URL: http://www.mironov.ru/council/initiations/11.html. An English translation by Alexander Krivenyshev (edited by Michael Cofield) is available at Worldtimezone.com at the following URL: http://www.worldtimezone.com/dst_news/dst_news_russia02.html Regards, Alexander Krivenyshev, http://www.worldtimezone.com New York, NY

New DST dates for Mauritius - moved to October
by Steffen Thorsen July 24, 2008

July 24, 2008

According to http://www.lexpress.mu/display_article.php?news_id=111216 (in French), Mauritius will start and end their DST a few days earlier than previously announced (2008-11-01 to 2009-03-31). The new start date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time given, but it is probably at either 2 or 3 wall clock time). A little strange though, since the article says that they moved the date to align itself with Europe and USA which also change time on that date, but that means they have not paid attention to what happened in USA/Canada last year (DST ends first Sunday in November). I also wonder why that they end on a Friday, instead of aligning with Europe which changes two days later. Best regards, Steffen / timeanddate.com

C-Eur related change suggestions for version 2008e
by Jesper Norgaard Welen July 20, 2008

July 20, 2008

In a previous email Robbin Kawabata has shown unintended changes for the tz database relating to the change for the C-Eur Rule in 2008d. Here are the relevant portions of the tz database together with a few suggestions to mend it (with + and - as the first letter of the relevant lines): Rule C-Eur 1944 1945 - Apr Mon>=1 2:00s 1:00 S # Whitman gives 1944 Oct 7; go with Shanks & Pottenger. Rule C-Eur 1944 only - Oct 2 2:00s 0 - Rule C-Eur 1945 only - Sep 16 2:00 0 - ... # These are for backward compatibility with older versions. ... # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone WET 0:00 EU WE%sT Zone CET 1:00 C-Eur CE%sT Zone MET 1:00 C-Eur ME%sT ... Zone Europe/Sofia 1:33:16 - LMT 1880 1:56:56 - IMT 1894 Nov 30 # Istanbul MT? 2:00 - EET 1942 Nov 2 3 :00 - 1:00 C-Eur CE%sT 1945 Apr 2 3:00 + 1:00 C-Eur CE%sT 1945 + 1:00 - CET 1945 Apr 2 3:00 2:00 - EET 1979 Mar 31 23:00 ... Zone Europe/Budapest 1:16:20 - LMT 1890 Oct 1:00 C-Eur CE%sT 1918 1:00 Hungary CE%sT 1941 Apr 6 2:00 - 1:00 C-Eur CE%sT 1945 May 1 23:00 + 1:00 C-Eur CE%sT 1945 1:00 Hungary CE%sT 1980 Sep 28 2:00s ... Zone Europe/Belgrade 1:22:00 - LMT 1884 1:00 - CET 1941 Apr 18 23:00 - 1:00 C-Eur CE%sT 1945 May 8 2:00s + 1:00 C-Eur CE%sT 1945 + 1:00 - CET 1945 May 8 2:00s 1:00 1:00 CEST 1945 Sep 16 2:00s The problem arose because the C-Eur rules had no DST for 1945, making other timezones free to use it without effects for 1945. However this meant that Zone CET and Zone MET did not have DST for 1945, which is not very adequate. I agree with the action of adding DST for C-Eur for 1945, but that means that other timezones using C-Eur must be changed to return status quo. As far as I can see only Europe/Sofia, Europe/Budapest and Europe/Belgrade are affected, though of course Europe/Skopje and other timezones linking to Europe/Belgrade will be equally affected. My suggestion for Europe/Sofia and Europe/Belgrade are to stop using C-Eur from 1945 since the timezone abbreviation (CET) will be the same, and then only start CEST from the previous cutoff dates. For Europe/Budapest the answer is easier since Hungary rule already has the DST start time of May 1, 1945 at 23:00 encoded, so the Hungary rule can simply be used insted of C-Eur since 1945. I don't have access to a zic compiler to see if the desired results crop out, so I will leave that to people who can check it.

proposed time zone package changes
by Arthur David Olson July 20, 2008

July 20, 2008

Proposed time zone packages appear below. These include: * changes to "Makefile" to allow withdrawal of logwtmp.c * data file URL fixes from Halasz Sandor Viktor * a fix for a typo in the "europe" file from Jesper Norgaard Welen (only affects 1945 time stamps) * changes for Mauritius in the "africa" file based on messages from Steffen Thorsen and Alex Krivenyshev * changes to the "leapseconds" file to reflect the IERS announcement of a positive leap second at the end of 2008 * changes (previously circulated) to the "tz-link.htm" file from Paul Eggert. If there's no negative feedback, I'll make tzcode2008e.tar.gz and tzdata2008e.tar.gz available on 2008-07-28. --ado diff -r -c old/Makefile new/Makefile *** old/Makefile Wed Mar 5 11:58:23 2008 --- new/Makefile Sun Jul 20 14:23:27 2008 *************** *** 1,4 **** ! # @(#)Makefile 8.6 # Change the line below for your time zone (after finding the zone you want in # the time zone files, or adding it to a time zone file). --- 1,4 ---- ! # @(#)Makefile 8.7 # Change the line below for your time zone (after finding the zone you want in # the time zone files, or adding it to a time zone file). *************** *** 246,258 **** TZCOBJS= zic.o localtime.o asctime.o scheck.o ialloc.o TZDSRCS= zdump.c localtime.c ialloc.c TZDOBJS= zdump.o localtime.o ialloc.o !

Re: proposed changes for Brazil, Mauritius, Argentina, Berlin 1945, etc.
by Robbin Kawabata July 16, 2008

July 16, 2008

Just wanted to mention a small discrepancy between the 2008d cover letter description and actual timezone behavior. The commentary says Berlin should have no user-visible changes. However, changes in the europe file affected past behavior for some European timezones including Berlin (see zdump output diffs below). It seems the "Changes affecting past time stamps" section should have mentioned some European timezones changed behavior for 1945 or 1947. Commentary from cover letter: ... Changes affecting past time stamps. * For Mauritius, also include the 1982/1983 DST as reported by Steffen Thorsen. * For America/Argentina/San_Luis, redo the history from 1990 through 2000 to match what's in Shanks & Pottenger. The following changes should not affect externally visible behavior. ... * Redo the daylight-saving rules for Berlin in 1945 to make it clearer that these are for the Soviet Zone, not for Berlin in general. ... ==================================================== Diffs between 2008c and 2008d zdump outputs (European timezones): 26a27,30 > CET Mon Apr 2 00:59:59 1945 UTC = Mon Apr 2 01:59:59 1945 CET isdst=0 > CET Mon Apr 2 01:00:00 1945 UTC = Mon Apr 2 03:00:00 1945 CEST isdst=1 > CET Sat Sep 15 23:59:59 1945 UTC = Sun Sep 16 01:59:59 1945 CEST isdst=1 > CET Sun Sep 16 00:00:00 1945 UTC = Sun Sep 16 01:00:00 1945 CET isdst=0 15,16c15,16 < Europe/Belgrade Tue May 8 00:59:59 1945 UTC = Tue May 8 01:59:59 1945 CET isdst=0 < Europe/Belgrade Tue May 8 01:00:00 1945 UTC = Tue May 8 03:00:00 1945 CEST isdst=1 --- > Europe/Belgrade Mon Apr 2 00:59:59 1945 UTC = Mon Apr 2 01:59:59 1945 CET isdst=0 > Europe/Belgrade Mon Apr 2 01:00:00 1945 UTC = Mon Apr 2 03:00:00 1945 CEST isdst=1 39,40c39,40 < Europe/Berlin Sun Apr 6 00:59:59 1947 UTC = Sun Apr 6 01:59:59 1947 CET isdst=0 < Europe/Berlin Sun Apr 6 01:00:00 1947 UTC = Sun Apr 6 03:00:00 1947 CEST isdst=1 --- > Europe/Berlin Sun Apr 6 01:59:59 1947 UTC = Sun Apr 6 02:59:59 1947 CET isdst=0 > Europe/Berlin Sun Apr 6 02:00:00 1947 UTC = Sun Apr 6 04:00:00 1947 CEST isdst=1 35,36c35,36 < Europe/Budapest Tue May 1 21:59:59 1945 UTC = Tue May 1 22:59:59 1945 CET isdst=0 < Europe/Budapest Tue May 1 22:00:00 1945 UTC = Wed May 2 00:00:00 1945 CEST isdst=1 --- > Europe/Budapest Mon Apr 2 00:59:59 1945 UTC = Mon Apr 2 01:59:59 1945 CET isdst=0 > Europe/Budapest Mon Apr 2 01:00:00 1945 UTC = Mon Apr 2 03:00:00 1945 CEST isdst=1 15,16C15,16 < Europe/Ljubljana Tue May 8 00:59:59 1945 UTC = Tue May 8 01:59:59 1945 CET isdst=0 < Europe/Ljubljana Tue May 8 01:00:00 1945 UTC = Tue May 8 03:00:00 1945 CEST isdst=1 --- > Europe/Ljubljana Mon Apr 2 00:59:59 1945 UTC = Mon Apr 2 01:59:59 1945 CET isdst=0 > Europe/Ljubljana Mon Apr 2 01:00:00 1945 UTC = Mon Apr 2 03:00:00 1945 CEST isdst=1 15,16c15,16 < Europe/Podgorica Tue May 8 00:59:59 1945 UTC = Tue May 8 01:59:59 1945 CET isdst=0 < Europe/Podgorica Tue May 8 01:00:00 1945 UTC = Tue May 8 03:00:00 1945 CEST isdst=1 --- > Europe/Podgorica Mon Apr 2 00:59:59 1945 UTC = Mon Apr 2 01:59:59 1945 CET isdst=0 > Europe/Podgorica Mon Apr 2 01:00:00 1945 UTC = Mon Apr 2 03:00:00 1945 CEST isdst=1 15,16c15,16 < Europe/Sarajevo Tue May 8 00:59:59 1945 UTC = Tue May 8 01:59:59 1945 CET isdst=0 < Europe/Sarajevo Tue May 8 01:00:00 1945 UTC = Tue May 8 03:00:00 1945 CEST isdst=1 --- > Europe/Sarajevo Mon Apr 2 00:59:59 1945 UTC = Mon Apr 2 01:59:59 1945 CET isdst=0 > Europe/Sarajevo Mon Apr 2 01:00:00 1945 UTC = Mon Apr 2 03:00:00 1945 CEST isdst=1 15,16c15,16 < Europe/Skopje Tue May 8 00:59:59 1945 UTC = Tue May 8 01:59:59 1945 CET isdst=0 < Europe/Skopje Tue May 8 01:00:00 1945 UTC = Tue May 8 03:00:00 1945 CEST isdst=1 --- > Europe/Skopje Mon Apr 2 00:59:59 1945 UTC = Mon Apr 2 01:59:59 1945 CET isdst=0 > Europe/Skopje Mon Apr 2 01:00:00 1945 UTC = Mon Apr 2 03:00:00 1945 CEST isdst=1 13,14c13,14 < Europe/Sofia Mon Apr 2 01:59:59 1945 UTC = Mon Apr 2 02:59:59 1945 CET isdst=0 < Europe/Sofia Mon Apr 2 02:00:00 1945 UTC = Mon Apr 2 04:00:00 1945 EET isdst=0 --- > Europe/Sofia Mon Apr 2 00:59:59 1945 UTC = Mon Apr 2 01:59:59 1945 CET isdst=0 > Europe/Sofia Mon Apr 2 01:00:00 1945 UTC = Mon Apr 2 03:00:00 1945 EET isdst=0 15,16c15,16 < Europe/Zagreb Tue May 8 00:59:59 1945 UTC = Tue May 8 01:59:59 1945 CET isdst=0 < Europe/Zagreb Tue May 8 01:00:00 1945 UTC = Tue May 8 03:00:00 1945 CEST isdst=1 --- > Europe/Zagreb Mon Apr 2 00:59:59 1945 UTC = Mon Apr 2 01:59:59 1945 CET isdst=0 > Europe/Zagreb Mon Apr 2 01:00:00 1945 UTC = Mon Apr 2 03:00:00 1945 CEST isdst=1 26a27,30 > MET Mon Apr 2 00:59:59 1945 UTC = Mon Apr 2 01:59:59 1945 MET isdst=0 > MET Mon Apr 2 01:00:00 1945 UTC = Mon Apr 2 03:00:00 1945 MEST isdst=1 > MET Sat Sep 15 23:59:59 1945 UTC = Sun Sep 16 01:59:59 1945 MEST isdst=1 > MET Sun Sep 16 00:00:00 1945 UTC = Sun Sep 16 01:00:00 1945 MET isdst=0 ==================================================== Diffs of europe file: *** 2008c/europe Mon Mar 24 05:30:58 2008 --- 2008d/europe Mon Jul 7 06:45:31 2008 *************** *** 1,2 **** ! # @(#)europe 8.12 # <pre> --- 1,2 ---- ! # @(#)europe 8.14 # <pre> *************** *** 459,461 **** # The most recent directive covers the years starting in 2002.

Possible C-Eur typo
by Jesper Norgaard Welen July 13, 2008

July 13, 2008

I found what is probably a typo of 2:00 which should perhaps be 2:00s in the C-Eur rule from tz database version 2008d (this part was corrected in version 2008d). The circumstancial evidence is simply the tz database itself, as seen below: Zone Europe/Paris 0:09:21 - LMT 1891 Mar 15 0:01 0:00 France WE%sT 1945 Sep 16 3:00 Zone Europe/Monaco 0:29:32 - LMT 1891 Mar 15 0:00 France WE%sT 1945 Sep 16 3:00 Zone Europe/Belgrade 1:22:00 - LMT 1884 1:00 1:00 CEST 1945 Sep 16 2:00s Rule France 1945 only - Sep 16 3:00 0 - Rule Belgium 1945 only - Sep 16 2:00s 0 - Rule Neth 1945 only - Sep 16 2:00s 0 - The rule line to be changed is: Rule C-Eur 1945 only - Sep 16 2:00 0 - It seems that Paris, Monaco, Rule France, Rule Belgium all agree on 2:00 standard time, e.g. 3:00 local time.
