I'm trying to determine the instant when clocks in time-zone-shifting parts of Russia changed in September 2011, using sources provided by Alexander Krivenyshev and Tobias Conradi.
One source is... http://government.ru/gov/results/16355/ ...which, according to translate.google.com, begins "Decree of August 31, 2011 No 725" and contains no other dates or "effective date" information.
Another source is... http://www.rg.ru/2011/09/06/chas-zona-dok.html ...which, according to translate.google.com, begins "Resolution of the Government of the Russian Federation on August 31, 2011 N 725" and also contains "Date first official publication: September 6, 2011 Posted on: in the "RG" - Federal Issue number 5573 September 6, 2011" but whcih does not contain any "effective date" information.
Another source is... http://en.wikipedia.org/wiki/Oymyakonsky_District#cite_note-RuTime-7 ...which, in note 8, contains "Resolution #725 of August 31, 2011... Effective as of after 7 days following the day of the official publication" but which does not contain any reference to September 6, 2011.
According to the law (see http://base.garant.ru/10123081/ or http://base.consultant.ru/cons/cgi/online.cgi?req=doc;base=LAW;n=121781;fld=...) the date when the resolution come into effect depends whether it affects the rights, freedoms and duties of people. If yes, then it come into effect simultaneously on the entire territory of the Russian Federation upon the expiry of 7 days after the day of its first official publication, that is, after 6+7=13 of September. If no, then it come into effect from the date of signing, that is, August 31. From my PoV, it is the first case.
Tobias Conradi combines Wikipedia's "on or after 7 days following the day of the official publication" with www.rg.ru's "Date of first official publication: September 6, 2011" to get September 13, 2011 as the cutover date (unusually, a Tuesday, as Tobias Conradi notes).
None of the sources indicates a time of day for changing clocks.
I suppose there was no actual clock change. The resolution #725 is not about changing clocks, it contains no such instructions whatsoever.
Is September 13 the right date? What's the right time of day?
Assuming that the day is "after September 13", one can suppose it should be 00:00 of September 14. -- ldv
