The display name will not change. Therefore, users in the "Vladivostok Standard Time" time zone do not have to manually update any settings. However, users in the "Magadan Standard Time" time zone must manually select “Russia Time Zone 9” as their new time zone setting after October 26, 2014. The Magadan Standard Time” item will be removed from the time zone list in the December 2014 DST Cumulative Update. The following exceptions apply to users who are currently in the “Magandan Standard Time” time zone:
-
Users in the Magadan Oblast region must manually switch to "Russian Time Zone 9."
-
Users who are in the Chukotsky Avtonomny Okrug (Chukotka) and Kamchatsky Krai (Kamchatka) regions must manually switch to "Russia Time Zone 11."

-
All other values remain the same as for the current "Kaliningrad Standard Time" time zone
Effect on users Users in Belarus who are located in the current "Kaliningrad Standard Time" time zone must manually switch to the new "Belarus Standard Time" time zone. Otherwise, these users will automatically be updated to the new "Russia Time Zone 1" on October 26, 2014.

The following are the known issues in this update.
-
No automatic time zone selection for some users Windows XP Embedded and Windows Server 2003 users cannot automatically select the correct new time zone after they install this update. Instead, users on these platforms can select the new time zone from the Time Zone list in the Date and Time Properties item in Control Panel that is shown in the following screen shot.
tzchange.exe /c <timezone name>
Note In this command, <timezone name> is the registry key name of the corresponding time zone in the system registry under the "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones subkey. This parameter is also the same as the current name of a time zone. Users who are currently in the "Kaliningrad Standard Time" time zone and who are running Windows Server 2003 must manually set the time zone after they install this update. To do this, these users must either manually select "(UTC+02:00) Kaliningrad (RTZ 1)" in the Time Zone list in the Date and Time Properties item in Control Panel or run the following command at a command prompt:
tzchange.exe /c "Kaliningrad Standard Time"
-
Historical data query not maintained after new time zone is selected After a user switches to another time zone, Windows does not maintain its past time zone settings. If the newly selected time zone has a different UTC offset from the previous selection, any queried date and time information may be incorrect if the time period of the query occurs before the time at which the time zone setting change is made. This issue applies to users who manually switch to "Russia Time Zone 3," "Russia Time Zone 10," "Russia Time Zone 11," or "Belarus Standard Time." This issue also applies to users who manually switch from "Magadan Standard Time" to "Russia Time Zone 9."
-
"Date out of range” message on Windows Vista and Windows Server 2008 After this update is installed on Windows Vista or Windows Server 2008, users see the following message in the Date and Time Properties item in Control Panel between October 26, 2014 at 02:00 and January 1, 2015 at 00:00 (midnight):
Daylight Saving Time ends on [Date out of range] at 12:00 AM. The clock is not set to adjust for this change.
Daylight Saving Time is not observed by this time zone.
-
Incorrect DST settings for future years on Windows Server 2003 and Windows XP Embedded If users install this update on Windows Server 2003 or Windows XP Embedded, their systems will continue to use the DST settings for 2014 even after the calendar year changes. This can cause the system to display the time incorrectly. To resolve this problem, users should install the December Cumulative Update (scheduled to be released in December, 2014) before the calendar year changes. After users install both the Russian time zone update and the December Cumulative Update, their systems will apply the correct DST settings and continue to display the correct time after the end of the 2014 calendar year.
