eight ".png" scan files are available.<br><br>1992 Decree sections have bold headings; the headings include (in sequence):<br> "2-M 3-M"<br> "3-M 4-M"<br> "4-M 5-M"<br> "5-M 6-M"<br>
"6-M 7-M"<br> "7-M 8-M"<br> "8-M 9-M"<br> "9-M 10-M"<br> "10-M 11-M"<br> "11-M 12-M"<br>The sections seem to cover time zones from west to east.<br>
<br>"อฯำหฯืำหฯล" ("Moscow") appears in the "2-M 3-M" section.<br>"ํมวมฤมฮำหมั" ("Magadan") appears in the "10-M 11-M" section.<br>The difference of eight between "2" and "10" matches the difference<br>
in hours between Moscow time and Magadan time.<br>So we should have these associations:<br><br> "2-M 3-M" Moscow<br> "3-M 4-M" Moscow+1<br> "4-M 5-M" Moscow+2<br> "5-M 6-M" Moscow+3<br>

<br>"๕ำิุ-ํมสำหษส" ("Ust-Maya" or "Ust-Maysky" or "Ust'-Majskij")<br>appears in the "8-M 9-M" (Moscow+6, Asia/Yakutsk) section of 1992's Decree 23.<br>This matches 2011's Decree 725.<br>

tzdata2011k's "europe" file has it as part of Asia/Vladivostok.<br>It must have shifted at some unknown instant between 1992 and 2011;<br>we need a new zone (Asia/Khandyga) for Tomponsky.<br><br>"๏สอัหฯฮำหษส" ("Oimkayon" or "Ojmyaknoskij") <br>

I can't find any instance of "๋ีาษฬุำหษส" or "๋ีาษฬุำหษล" ("Kuril") in 1992's decree.<br>2011's Decree 725 has most of the Sakhalin Oblast (including the "South-Kuril region")<br>
at Moscow+7 and has the "North-Kuril region" at Moscow+8.<br>tzdata2011k's "europe" file has an Asia/Sakhalin zone<br>and no Kuril zones (but some Kuril comments).<br>tzdata2011k's Asia/Sakhalin is Moscow+8 until 1997-03-20 02:00:00,<br>
Moscow+7 thereafter; Gwillim Law's IATA SSIM research<br>led to the conclusion that Sakhalin (in particular, Yuzhno-Sakhalin)<br>switched in 1997 (while all the Kurils remained at Moscow+8).<br>We need a new zone (Asia/Severo-Kirilsk) for North-Kuril if that area was<br>
indeed Moscow+7 in 1992 and is Moscow+8 now.<br>We need a new zone (Asia/Yuzhno-Kirilsk) for South-Kiril if that area did<br>indeed begin to differ from Asia/Sakhalin in 1997.<br><br>"๎ฯืฯำษยษาำห" ("Novosibirsk")<br>
appears in the "5-M 6-M" (Moscow+3) section of 1992's Decree 23.<br>2011's Decree 725 also has Novosibirsk at Moscow+3.<br>However, tzdata2011k's "europe" file claims that it was at Moscow+4 until 1993-05-23.<br>
<br>"๔ฯอำหมั" ("Tomsk")<br>appears in the "5-M 6-M" (Moscow+3) section of 1992's Decree 23.<br>2011's Decree 725 also has Tomsk at Moscow+3.<br>However...<br> <a href="http://newsru.com/russia/01may2002/clock.html">http://newsru.com/russia/01may2002/clock.html</a><br>
...claims that it switched from Moscow+4 to Moscow+3 on 2002-05-01<br>(if <a href="http://translate.google.com">translate.google.com</a> is correct).<br><br>We also have...<br> # From Stanislaw A. Kuzikowski (1994-06-29):<br>
# But now it is some months since Novosibirsk is 3 hours ahead of Moscow!<br> # I do not know why they have decided to make this change;<br> # as far as I remember it was done exactly during winter->summer switching<br>
# so we (Novosibirsk) simply did not switch.<br> # Tomsk is still 4 hours ahead of Moscow.<br>...which would indicate that Novosibirsk and Tomsk switched from Moscow+4 to Moscow+3<br>(and at different instants to boot).<br>
<br>It looks as if we need an Asia/Tomsk zone (Tomsk being the most populous city in<br>Tomsk Oblast). Since folks in Tomsk can use the Novosibirsk rules for current times,<br>I'd hope to get better information on time history in Tomsk and Novobirsk<br>
(in particular if and when there were transitions from Moscow+4 to Moscow+3)<br>before creating the new zone.<br><br> --ado<br><br><br><br><br><br><br><br><br><br><br><br>
