Ukraine 1990, PS
by Bogdan Krusiński March 16, 2014

March 16, 2014

google translator gone mad - translates ukrainian word 'bes' ("without") as 's' ("with") (i tried both translating into polish and eglish, both translations are opposite to what was in orginal). The decree from june 1990 do not mentions previous zone - just states that country moves to zone +2 GMT without addition of one hour (without DST) ie +2 GMT. with best regards Bogdan Krusiński

Ukraine 1990
by Bogdan Krusiński March 15, 2014

March 15, 2014

Hello, the contenst of decree at http://search.ligazakon.ua/l_doc2.nsf/link1/T001500.html contain only one point: "1. Установити з 1 липня 1990 року на території Української РСР час другого часового поясу без додання однієї години." "1. Intorduction from 1st of July 1990 on territory of Ukrainian SSR time of two hours without addition of one hour". I'm a bit disturbed because I was directed by astro.com to these archives where it is translated as: "Set on 1 July 1990 in the Ukrainian SSR, the second time zone with the addition of one hour." "without" is not "with". Pozdrawiam serdecznie Bogdan Krusiński http://www.astrologia.pl

Time on Johnston Island
by Lyle March 12, 2014

March 12, 2014

While doing research on atomic bomb testing, I found that at one point, when JI was being used for that testing, the time being used was not Hawaiian time but rather the same time being used on the ships, which had a GMT offset of -11 hours. This apparently applied to at least the time from Operation Newsreel (Hardtack I/Teak shot, 1968-8-1) to the last Operation Fishbowl shot (Tightrope, 1962-11-4). The document that lead us to that conclusion is by Herman Hoerlin, "The United States High-Altitude Test Experience: A Review Emphasizing the Impact on the Environment", Los Alamos LA-6405, Oct 1976. Fas.org/sgo/othergov/doe/lanl/docs1/00322994.pdf. See the table on page 4 where he lists GMT and local times for the tests; a footnote for the JI tests reads that local time is "JI time = Hawaii Time Minus One Hour". A little give-back for the use of your database in informing the atomic test tables on Wikipedia. Thanks. Lyle McElhaney Lmc(a)ashabon.com

Windows 8.1 and tz data?
by Donald MacQueen March 10, 2014

March 10, 2014

In the email announcement titled " 2014a release of tz code and data available", there is this statement: Microsoft Windows 8.1 and later support tz database names. I did not see this mentioned on the tz list and an hour's googling brings me no joy. Does anyone have any links that will ease my confusion?

No Virgin Islands Data
by Hank W. March 7, 2014

March 7, 2014

The data for the Virgin Islands, both British & US, is missing. I checked an old dataset (2012j) and found them at the end of the northamerica file. They have since been replaced by a note saying 'see southamerica', but they're not in the southamerica file, either. Hank W., Austin, Texas, USA

Possible error in Europe/Kiev for 1991 - 1992
by Alois Treindl March 7, 2014

March 7, 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
