  • Cumulative time zone updates contain only data that has changed for a specific region or that has been added to maintain parity with other operating system versions. Therefore, if a time zone key has been deleted, some original values may not be restored after you apply the cumulative zone update.

    We do not recommend that you delete any registry keys that are related to time zones. On a computer that has incomplete time zone keys, first restore the time zone keys from a known good backup. Then, apply the update.

Known issues

When you install this update on a computer that is running Windows Server 2003 with SP1, and you then install Windows Server 2003 SP2, Bucharest no longer appears in the display name of the GTB time zone. GTB Standard Time appears as "(GMT+02:00) Athens, Beirut, Istanbul, Minsk" instead of as "(GMT+02:00) Athens, Bucharest, Istanbul." This issue will be corrected in a future update. To work around this issue, you can use the Time Zone Editor (Tzedit.exe) to modify the display name. Or, you can type the following command at the command prompt:

%systemroot%\system32\tzchange.exe /F"GTB Standard Time" /N"(GMT+02:00) Athens, Bucharest, Istanbul" The following file is available for download from the Microsoft Download Center:
