1) Since September 2011 - at least - there is disagreement between reported law and tzdb for current offsets in Bulunsky Ulus, Oymyakonsky Ulus, Tomponsky Ulus, Ust-Maysky Ulus which are located in Russia. On 2012-04-29 (http://mm.icann.org/pipermail/tz/2012-April/017639.html) it was defined by a TZ maintainer that: "The first order of business is to ensure that current (2012) time stamps are handled correctly throughout Russia." So, I assume the below could fall under first order of business. 2012-09-16 Alexander Krivenyshev reported differences http://mm.icann.org/pipermail/tz/2011-September/008798.html 2012-09-16 Tobias Conradi wondered whether there was a change in offset or the TZ DB simply contained false data Two zones are proposed in case the data is correct for the time before the decree took effect Asia/Khandyga (setup changed later) Asia/Ust-Nera containing Oymyakonsky http://mm.icann.org/pipermail/tz/2011-September/008799.html 2012-09-17 Arthur David Olson makes a summary http://mm.icann.org/pipermail/tz/2011-September/008818.html 2012-09-20 Tobias Conradi changes the proposal for Asia/Khandyga to only contain Tomponsky, Ust-Maysky http://mm.icann.org/pipermail/tz/2011-September/008836.html 2012-09-27 Arthur David Olson asks for old decree "Decree #725 indicates that it abrogates Decree #23 of January 8, 1992 (among other things abrogated); is the abrogated decree available online?" http://mm.icann.org/pipermail/tz/2011-September/008898.html 2012-09-27 Sanjeev Gupta provides a link to the scan http://government.consultant.ru/page.aspx?1223966 http://mm.icann.org/pipermail/tz/2011-September/008899.html 2012-10-02 Arthur David Olson makes some analysis of the data http://mm.icann.org/pipermail/tz/2011-October/008933.html 2012-10-02 Yury Tarasievich clarifies that the sections contain border descriptions and additionally writes "BTW, the document only notes the possibility, but doesn't explicitly refer to the then actual (Soviet) practice for the large territories to observe the zonal time of the neighbouring timezone." http://mm.icann.org/pipermail/tz/2011-October/008935.html Now follows my interpretation of http://government.consultant.ru/page.aspx?1223966 (granitsa mezhdy = border between) page 5 section about Zone 8 - Zone 9 border Zone 8/left: Bulunsky Raion Zone 9/right: Ust-Maysky Raion + Tomponsky Raion page 6 section about Zone 9 - Zone 10 border Zone 10/right: Oymyakonsky Raion Which, except for Bulunsky Raion, is what according to "tzdata2012c/europe" Oscar van Vlijmen did report, but no sources were cited for. That would mean that: A) two zones need to be created: Asia/Ust-Nera Oymyakonsky Ulus Asia/Khandyga Tomponsky Ulus, Ust-Maysky Ulus both zones observing a change in offset towards Moscow Time in September 2011, exact time see below. B) Bulunsky Ulus needs a fix. Either 2009-11-29 Oscar van Vlijmen report is correct, then a new zone is needed or it is not correct, then the report should be removed or marked deprecated and the data from the 1992 decree could be used for the time before the 2011 decree became effective. Time of change: http://en.wikipedia.org/wiki/Oymyakonsky_District#cite_note-RuTime-7 "Опубликован: "Российская Газета", No.197, 6 сентября 2011 г" My translation: ~Published ..... 2011-09-06 "Effective as of after 7 days following the day of the official publication." which would mean the law became effective 2011-09-13 a Tuesday. http://www.rg.ru/2011/09/06/chas-zona-dok.html "Дата первой официальной публикации: 6 сентября 2011 г" My translation: First official publication 2011-09-06. Note: That all leaves out effects as mentioned in the above cited 2012-10-02 comment by Yury Tarasievich. Maybe there was no offset change relative to Moscow Time, so no zones are needed. But in absence of reports supporting deviation from the 1992 decree boundaries for any of the four raion/ulus I would follow the 1992 decreed zone boundaries. 2) Law 2011 Sakha Republic is split by decree #725 http://government.ru/gov/results/16355/ between Zone 7 - Moscow Time + 6 ...Bulunskij, Tomponskij, Ust'-Majskij... Zone 8 - Moscow Time + 7 ...Ojmyakonskij... Zone 9 - Moscow Time + 8 3) TZDB 2012 tzdata2012c\europe splits Sakha as follows # From Oscar van Vlijmen (2009-11-29): # The Sakha districts are: Aldanskij, Amginskij, Anabarskij, # Verkhnevilyujskij, Vilyujskij, Gornyj, # Zhiganskij, Kobyajskij, Lenskij, Megino-Kangalasskij, Mirninskij, # Namskij, Nyurbinskij, Olenyokskij, Olyokminskij, # Suntarskij, Tattinskij, Ust'-Aldanskij, Khangalasskij, # Churapchinskij, Eveno-Bytantajskij Natsional'nij.
