I note in the iana time zone database for Europe that it states the following # From Alexander Krivenyshev (2011-06-14): # According to Kremlin press service, Russian President Dmitry Medvedev # signed a federal law "On calculation of time" on June 9, 2011. # According to the law Russia is abolishing daylight saving time. # # Medvedev signed a law "On the Calculation of Time" (in russian): # <a href="http://bmockbe.ru/events/?ID=7583"> # http://bmockbe.ru/events/?ID=7583 # </a> # # Medvedev signed a law on the calculation of the time (in russian): # <a href="http://www.regnum.ru/news/polit/1413906.html"> # http://www.regnum.ru/news/polit/1413906.html # </a> # From Arthur David Olson (2011-06-15): # Take "abolishing daylight saving time" to mean that time is now considered # to be standard. Note that an Oracle Support document (reference Russia abandons DST in 2011 - Impact on Oracle RDBMS [ID 1335999.1]) relating to the change in Russia includes the following information Russian State Duma passed the third reading of the bill 509727-5 "On the Calculation of Time" (in Russia) and adopted a law abolishing the transition to daylight saving time. The old rule was to move back on last Sunday of October (30 October 2011) The Russian timezones will stay on the "summertime". For Questions/official statements about the DST change itself, please contact the Russian Government I think this is contrary to Mr Olsons assertion that abolishing now means standard.

Russian State Duma passed the third reading of the bill 509727-5 "On the Calculation of Time" (in Russia) and adopted a law abolishing the transition to daylight saving time. The old rule was to move back on last Sunday of October (30 October 2011) *The Russian timezones will stay on the "summertime".* For Questions/official statements about the DST change itself, please contact the Russian Government
there is one actual factual error in my note, "adopted a law abolishing the transition *to* daylight saving time." should be "adopted a law abolishing the transition *from* daylight saving time." and "*The Russian timezones will stay on the "summertime". *might be better worded as*"**The Russian timezones will stay on the same time as in the summer".* I'll update this on monday aldo it's rather old news these days and the note is archived
I think this is contrary to Mr Olsons assertion that abolishing now means standard.
My DST notes intention is to simply /reflect/ the iana changes and are not meant to be authoritative , It is documented Oracle uses the IANA database as source, so whatever is in there is for Oracle "authoritative" regarding TZ's Regards, Gunther

I think you misread what ado intended to say. I believe his intent was that the new timezone for Russia (an offset from UTC which used to be its Summertime) can now be considered as standard time for Russia (or standard times, as there are still multiple zones right?) rather than being considered summer time. He wasn't intending to say that the time would revert to what had been standard time before. kre

I think that the question we need to answer is: should the Russian time zones now have the "isdst" flag permanently set to 0 (for standard time), or permanently set to 1 (for daylight savings time)? I don't know what should be the case, but currently the Russian time zones have isdst=0. According to the output from "zdump -v Europe/Moscow", the last transition was from {isdst=0, gmtoff=10800} to {isdst=0, tzoff=14400}, on 27 Mar 2011. This transition corresponds to a one-hour jump in standard time, without either entering or leaving daylight savings time. Obviously, the Russian time zones should also have the correct offset from UTC, and I believe that they are correct in that regard. --apb (Alan Barrett)

The usual practice has been to not set the DST flag for time offsets that are permanent, or are the least of multiple offsets are used in one or more years. Some judgment is needed, as there's not always a sharp line between "permanent" and "temporary" (was the U.S. on permanent DST from 1942 to 1945, or was that temporary?) but the current Russian situation seems relatively permanent, so the DST flag isn't set there.
Is that a rule of the Russian Federation only, or can we apply it to the Falkland Islands? -----Original Message----- From: tz-bounces@iana.org [mailto:tz-bounces@iana.org] On Behalf Of Paul Eggert Sent: Sunday, July 7, 2013 21:58 To: Alan Barrett Cc: tz@iana.org Subject: Re: [tz] re DST in Russia 2011 On 07/07/2013 02:18 PM, Alan Barrett wrote:
