Important This update supersedes and replaces update KB931836, released in January 2007. This update also includes additional time zone changes that were signed in to law after update KB931836 was created. Customers who have already deployed update KB931836 should evaluate whether any of the five specific time zone changes that are addressed in the update described by this Microsoft Knowledge Base (KB) article merit deploying this update immediately. If systems are not directly affected, you can schedule deployment at the next available opportunity. We recommend that all customers standardize on the most current Windows cumulative time zone update to guarantee the consistency of the time zone database on all systems.

Important Before you apply the update that is described by this article, be aware of potential issues that may affect Microsoft Office Outlook.

For more information about these issues, click the following article number to view the article in the Microsoft Knowledge Base:

 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, applying the cumulative time zone update may not restore all the original values. We do not recommend or support the deletion of any registry keys that are related to time zones. On a computer that is in this state, first restore the time zone keys from a known good backup. Then, apply the update.



INTRODUCTION
The update that this article describes changes the time zone data to account for daylight saving time (DST) changes in several countries, as outlined. This update also includes other DST-related changes, time zone-related changes, and settings-related changes. Some of these changes will occur in 2007. Some of these changes have occurred since the products that are listed in the &quot;Applies to&quot; section were originally released. The update that this article describes is a cumulative update rollup that includes all the changes that were previously released in Microsoft Knowledge Base (KB) article 928388 and in KB article 929120. This update also describes some additional changes that have occurred since the last cumulative update in KB article 928388 and in KB article 931836.

Update cannot be installed as a newer or same time zone update has already been installed on the system.

This message indicates that you have already applied the correct update or that Windows Updates or Microsoft Update has automatically installed this update. No additional action is required to update the Windows operating system software.

Updates from the previous cumulative Windows time zone update
The following changes have been made since the previous Windows cumulative time zone update, described in KB article 931836:
 * Caucasus Standard Time

Changes display name to Caucasus Standard Time as cities in the previous display name have separate time zones, and removes DST settings.
 * Armenian Standard Time

Note Updates for the Caucasus time zone and the new Armenian time zone are not included in the Windows Vista RTM hotfix package for this issue. The Caucasus time zone and the Azerbaijan time zone have been separated since Windows Vista RTM, and they do not require an update. Windows Vista will receive all future updates to keep consistency in the Windows time zone registry structure.
 * New Zealand Standard Time

Adjusts DST start dates and end dates according to changes signed in to law after the prior cumulative time zone update was created (February 2007).
 * GTB Standard Time

Corrects the display name for GTB Standard Time on Windows Server 2003 SP2 to include Bucharest.
 * Jordan Standard Time

Adjusts DST start times, end times, and dates according to changes signed in to law after the prior cumulative time zone update was created (February 2007).



August 2007 cumulative DST and time zone settings
The following table outlines all the time zone changes that are included in this update.

Additional registry keys
In addition to the changes that are listed in the previous table, this update adds registry keys that store historical DST data for certain time zones. These keys are present in Windows Vista, and are included to keep parity in the Windows time zone registry structure.

Prerequisites
To install this update on a computer that is running Microsoft Windows XP, you must have Windows XP SP2 installed.

To install this update on a computer that is running Windows Server 2003, you must have Windows Server 2003 SP1 or Windows Server 2003 SP2 installed on the computer.

Restart requirement
You do not have to restart the computer after you install this update.

Uninstalling the cumulative update rollup
Windows time zone updates for Windows XP and Windows Server 2003 include custom installation logic. This custom logic guarantees the correct installation of time zone updates and the correct state of the Windows time zone database. This custom logic also guarantees that when you uninstall the update, the time zone database returns to the DST rules that are in effect in the year 2006 across all time zones.

You can uninstall only the highest version of the cumulative update installed on the system. When you uninstall this version of the cumulative update, the time zone database reverts to the state that existed before the first update was installed. For example, if you install update 931836 in February 2007, and then you install cumulative update KB933360 in August 2007, you can uninstall only cumulative update KB933360. When you uninstall cumulative update KB933360, the time zone database will revert to the 2006 state, before any time zone updates were released. Additionally, if you install cumulative update KB933360, Windows will not let you install older cumulative updates such as KB931836 and KB928388.

Update replacement information
Note You can install this cumulative update rollup even after you have installed any of the following previously-released updates.

This update replaces the following updates:  

931836 February 2007 cumulative time zone update for Microsoft Windows operating systems

 

928388 2007 time zone update for Microsoft Windows operating systems

 

929120 Windows Server 2003-based computers and Windows XP-based computers that are set to the West Australia time zone do not change to daylight saving time on December 3, 2006

Known issues
When you install this update on a computer that is running Windows Server 2003 with Service Pack 1, and you then install Windows Server 2003 Service Pack 2, Bucharest no longer appears in the display name of the GTB time zone. GTB Standard Time appears as &quot;(GMT +02:00) Athens, Beirut, Istanbul, Minsk&quot; instead of as &quot;(GMT +02:00) Athens, Bucharest, Istanbul.&quot; 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&quot;GTB Standard Time&quot; /N&quot;(GMT+02:00) Athens, Bucharest, Istanbul&quot;

The following file is available for download from the Microsoft Download Center:
