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. It replaces old instructions, which can result in changes. Details supporting this have been provided at http://mm.icann.org/pipermail/tz/2012-May/017688.html
Still, it can be wrong, but then it would be nice to see evidence for an error in the above reasoning.
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. According to http://en.wikipedia.org/wiki/Daylight_saving_time_in_Russia DST changes have been carried out 02:00 local time.
So maybe the 00:00 is local time (before the change). But depending on the direction of the move that could mean a repetition of the time between 23:00 and 24:00 - has anyone seen that happening in Russia in the last 20 years? Maybe someone who can Google in Russian can search for changeover time, maybe trying to find 00:00 or 02:00? -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com/
