[tz] More Russian Changes

[Matt Johnson]

FYI - Two draft bills are posted on the Russian government's web site:

http://government.ru/activities/20702/
http://government.ru/activities/20703/

If approved, the effect would be to move the Astrakhan region from UTC+3 to UTC+4, and to move the Trans-Baikal region from UTC+8 to UTC+9.  Neither bill mentions an effective date.

It's not clear whether the Trans-Baikal region refers to the entire area of Zabaykalsky Krai or some subset.  Zabaykalsk Krai is currently managed by the Asia/Chita time zone, which I assume would remain intact and just get a new row in its zone entry.

Also, assuming by Astrakhan region they mean the Astrakhan Oblast, then I think this change would require a new time zone. I suggest Europe/Astrakan for the city of the same name in this region.  This is split from the Europe/Volograd time zone.
