Possible error in Europe/Kiev for 1991 - 1992
by Alois Treindl March 8, 2014

March 8, 2014

In western and Ukrainian astrology circles, there is on ongoing dispute about which timezone was in force in Kiev/Ukraine on the date the parliament decided about its independence, on 24 August 1991. Mostly, a timezone of GMT +3h is considered correct. This is in conflict with what TZ database states for that date. TZ database holds: # Most of Ukraine since 1970 has been like Kiev. Zone Europe/Kiev 2:02:04 - LMT 1880 2:02:04 - KMT 1924 May 2 # KievMTime 2:00 - EET 1930 Jun 21 3:00 - MSK 1941 Sep 20 1:00 C-Eur CE%sT 1943 Nov 6 3:00 Russia MSK/MSD 1990 3:00 - MSK 1990 Jul 1 2:00 2:00 - EET 1992 2:00 E-Eur EE%sT 1995 2:00 EU EE%sT Which makes reference to these DST rules #DST rules for Russia after WW2 Rule Russia 1981 1984 - Apr 1 0:00 1:00 S Rule Russia 1981 1983 - Oct 1 0:00 0 - Rule Russia 1984 1991 - Sep lastSun 2:00s 0 - Rule Russia 1985 1991 - Mar lastSun 2:00s 1:00 S Rule Russia 1992 only - Mar lastSat 23:00 1:00 S Rule Russia 1992 only - Sep lastSat 23:00 0 - Rule Russia 1993 2010 - Mar lastSun 2:00s 1:00 S Rule Russia 1993 1995 - Sep lastSun 2:00s 0 - Rule Russia 1996 2010 - Oct lastSun 2:00s 0 - #Modern EU rules Rule EU 1981 max - Mar lastSun 1:00u 1:00 S Rule EU 1996 max - Oct lastSun 1:00u 0 - # E-Eur differs from EU only in that E-Eur switches at midnight local time.

Via my US colleage David Cochrane, I received copies from a Moscow fellow, first name Vladimir, who reported several government documents, refering to Ukrainia timezones. Vladimir writes: --- quote Good news that now we have more documents online in Ukrainian language as well as Google translator. > why this decree states to go off DST when DST was not observed in Kiev in 1991. I did a research in laws and now we have an answer. Unfortunately, we should change a little our DST tables for Kiev and Ukraine. First in Ukraine they changed Time zone from UTC+3 to UTC+2 with DST: 03 25 1990 02:00 -03.00 1 Time Zone 3 with DST 07 01 1990 02:00 -02.00 1 Time Zone 2 with DST * Ukrainian Government's Resolution of 18.06.1990, No. 134. http://search.ligazakon.ua/l_doc2.nsf/link1/T001500.html They did not end DST in September, 1990 (according to the law, "summer time" was still in action): 09 30 1990 03:00 -02.00 1 Time Zone 2 with DST * Ukrainian Government's Resolution of 21.09.1990, No. 272. http://search.ligazakon.ua/l_doc2.nsf/link1/KP900272.html Again no change in March, 1991 ("summer time" in action): 03 31 1991 02:00 -02.00 1 Time Zone 2 with DST DST ended in September 1991 ("summer time" ended): 09 29 1991 03:00 -02.00 0 Time Zone 2, no DST * Ukrainian Government's Resolution of 25.09.1991, No. 225. http://www.uazakon.com/documents/date_21/pg_iwgdoc.htm This is an answer. Since 1992 they had normal DST procedure: 03 29 1992 02:00 -02.00 1 DST started 09 27 1992 03:00 -02.00 0 DST ended * Ukrainian Government's Resolution of 20.03.1992, No. 139. http://www.uazakon.com/documents/date_8u/pg_grcasa.htm ------ end quote I (Alois) interpret him like this: - On 1 Jan 1990, Kiev was on GMT + 3h (I call this 3he, 3 hours east). - on 25 March 1990, at 02:00 am, it went to DST, i.e. to 4he - on 1 July 1990, at 2:00 am, it shifted the standard time, kept the DST, moving effectively from 4he to 3he - no change on 30 Sept 1990, the kept DST, i.e. stayed on 3he (Russia ended DST on that data) - no change on 31 March 1991, Kiev stayed on 3he (Russia began DST on that data) - on 29 Sept 1991, at 03:00 am, Kiev ended DST, went to 2he - on 29 March 1992, 2:00 am, Kiev started DST, went to 3he - on 27 Sept 1992, 2:00 am, Kiev ended DST, went to 2he I have used Google translation to get the content of the links Vladimir provides: A) http://search.ligazakon.ua/l_doc2.nsf/link1/T001500.html " Set on 1 July 1990 in the Ukrainian SSR, the second time zone with the addition of one hour." This page says that Ukraine adopted 2he as standard time on 1 July 1990. One could interpret this that it talks about the timezone being 2he plus one hour. But I do not think it does. I think it means: Standard time moved to 2he, the clock was shifted west by one hour, i.e. one hour was added in the course of transition. (from h3e to h2e, if DST was not in force, or from h4e to h3e, if DST was in force). The statement does not confirm whether DST was in force or not at that data. B) http://search.ligazakon.ua/l_doc2.nsf/link1/KP900272.html states that on 30 Sept 1990, Ukraine did not turn clocks back, but continues to use DST. This implies that DST was indeed in force, at that time. C) http://www.uazakon.com/documents/date_21/pg_iwgdoc.htm states that on 29 September 1991, DST was ended and clocks set back by one hour. My conclusion is: TZ database missed the onset of DST in March 1990, and in consequence, missed its end in September 1991. The goverment document C) clearly states that DST ended in Ukraine on 29 Sept 1991, a date when TZ database says that DTS was not in force. I propose this correction of Europe/Kiev Zone Europe/Kiev 2:02:04 - LMT 1880 2:02:04 - KMT 1924 May 2 # KievMTime 2:00 - EET 1930 Jun 21 3:00 - MSK 1941 Sep 20 1:00 C-Eur CE%sT 1943 Nov 6 3:00 Russia MSK/MSD 1990 Jul 1 2:00 2:00 1:00 EET 1991 Sep 29 3:00 2:00 E-Eur EE%sT 1995 2:00 EU EE%sT

timezone 2014 : Turkey delays DST start by one day
by Semih Sakiz Feb. 27, 2014

Feb. 27, 2014

Hello, According to Turkish government decision, there will be one-day delay in the start of DST. DST start time will be "2014 Monday, 31 March" instead of "2014 Sunday, 30 March" on Turkey. Is there a plan to update the time zone database for this change ? The latest timezone data on the URL "http://www.iana.org/time-zones" contains Time Zone Data v. 2013i and does not include the latest change in TURKEY. Here you can find the links for the change. http://www.timeanddate.com/news/time/turkey-starts-dst-2014.html https://bugzilla.redhat.com/show_bug.cgi?id=1065926 http://www.resmigazete.gov.tr/main.aspx?home=http://www.resmigazete.gov.tr/… [Description: Description: Poligon thy:2013:subat:mail imza:logo-tek-satir.png] Semih SAKIZ | Sistem Programcısı / System Programmer Türk Hava Yolları A.O.

Chile Time Change

Feb. 19, 2014

That much notice would be a blessing. In years before 2013, the changes were made with as little as 5 days notice (notice Monday for a change in the date scheduled for the following Saturday). And as I said before, we have a goverment change on March 11, so all bets are off. -G.
