[tz] [PATCH 5/5] Update zone.tab for Russia, and remove Asia/Tiksi comment.

Tue Jul 8 05:26:55 UTC 2014


My best guess is that the Asia/Tiksi entry is a false alarm,
and that the area hasn't diverged from Yakutsk since 1970.
* europe: Move zone.tab comments to zone.tab.
(Asia/Yakutsk): Move comment for Bulunsky district here,
Remove a comment about a draft Asia/Tiksi zone, containing the
Bulunsky district.  We don't have sufficient evidence that it
ever diverged from Yakutsk after 1970.
* zone.tab (RU): Reorder entries to make more geographical sense.
Add comments for draft zones Asia/Chita, Asia/Srednekolymsk.
(Europe/Samara, Asia/Novokuznetsk, Asia/Magadan, Asia/Kamchatka)
(Asia/Anadyr): Mention that the Moscow offset changes 2014-10-26.
* NEWS: Document the above.

     2014-10-26 at 02:00 local time.  (Thanks to Alexander Krivenyshev.)
-    The affected zones are Europe/Kaliningrad, Europe/Moscow,

-    two new zones will be needed soon: Asia/Chita (split from Asia/Yakutsk,
-    and also with two hours subtracted) and Asia/Srednekolymsk (split from
-    Asia/Magadan, but with only one hour subtracted).  (Thanks to Tim Parenti
-    for pointing out the need for the latter zone.)  Additionally, a new zone
-    Asia/Tiksi (split from Asia/Vladivostok) will be needed to fix some history
-    before 2011.  (Thanks to Tim Parenti.)  All three of these new zones will
-    be deferred until the change is official; for now they are commented out.
+    There are a few exceptions: Magadan Oblast (Asia/Magadan) and Zabaykalsky

+    (Asia/Novokuznetsk), and the Samara Oblast and the Udmurt Republic
