According to a recent law [ link ] passed by the government of Russia, Russia will change its existing time zones on October 26, 2014.


Microsoft is planning to release an update for Windows on September 23, 2014 to address this change, with details below:



1.  Update 7 existing time zones to match with the new ones

Yakutsk Standard Time



(UTC+10:00) Yakutsk



Impact on users: None. Users who fall into these new time zones will have their settings automatically updated on Oct 26, 2014.



2.  Add 3 new time zones



New Name of Time Zone



New Display Name



Current Name of Time Zone



Current Display Name



Russia Time Zone 3



(UTC+04:00) Izhevsk, Samara (RTZ 3)

Russia Time Zone 10



(UTC+11:00) Chokurdakh (RTZ 10)



N/A



N/A



Russia Time Zone 11



(UTC+12:00) Anadyr, Petropavlovsk-Kamchatsky (RTZ 11)



N/A



N/A



Impact on users: Users who fall into these new time zones will need to manually switch to the new time zones, otherwise will remain in the current selected ones which will not be correct anymore for their region after Oct 26, 2014.



3.  Merge two existing time zones to a new one



New Name of Time Zone



New Display Name



Current Name of Time Zone



Current Display Name



Russia Time Zone 9



(UTC+10:00) Vladivostok, Magadan (RTZ 9)



Vladivostok Standard Time /



Magadan Standard Time



(UTC+11:00) Vladivostok /



(UTC+12:00) Magadan



Impact on users: Windows will update “Vladivostok Standard Time” to the new time zone completely, and update time data only for "Magadan Standard Time" but leave the display/time zone name as is, so the user on the Vladivostok time zone won’t need to do anything (just as #1 above), but those on the other will need to manually switch in order to get the correct name. If they don’t, they’ll still have the correct time data after October 26, 2014, till Windows deprecates the "Magadan Standard Time" time zone in a later milestone, when they will have to switch.



4.  Create new time zone for Belarus


Belarus is currently sharing time zone setting with Kaliningrad, so Windows will create a new "Belarus Standard Time" as part of this update.




  • Time zone name: Belarus Standard Time




  • Display name: (UTC+03:00) Minsk




  • All other value remain the same as the current “Kaliningrad Standard Time” time zone




Impact on users: Users in Belarus who fall into the "Kaliningrad Standard Time" time zone will need to manually switch to this new time zone, otherwise will be automatically updated to the new "Russia Time Zone 1" on October 26, 2014.



Note: Applicable systems for this update will be the same as those for the latest cumulative update, and all systems will need to have the latest cumulative update installed before this update can be applied. You can find the latest time zone cumulative update for Windows here .
