INTRODUCTION

Starting in the spring of 2007, daylight saving time (DST) start and end dates for the United States will transition to comply with the Energy Policy Act of 2005. DST dates in the United States will start three weeks earlier, at 2:00 A.M. on the second Sunday in March. DST will end one week later, at 2:00 A.M. on the first Sunday in November.

The update that this article describes changes the time zone data to account for the DST change for the United States. 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 "Applies To" 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 articles 928388 and 929120. This update also describes some additional changes since the last cumulative update in Microsoft Knowledge Base article 928388.

Note When you apply this update, you may receive the following message:
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 your Windows operating system software.

RESOLUTION

Update information

Prerequisites

To install this update on a computer that is running Microsoft Windows XP, you must have Windows XP Service Pack 2 installed.

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 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. 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 928388 in December 2006, and then you install cumulative update 931836 in February 2007, you can uninstall only cumulative update 931836. When you uninstall cumulative update 931836, the time zone database will revert to its pre-December state. Additionally, if you install cumulative update 931836, Windows will not let you install update 928388.

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:
  • 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

Mexico time zones

Three new time zones have been added for Mexico on Windows XP and Windows Server 2003 to keep the time zone databases in parity with Vista. The new time zones are required because some time zones that Mexico previously shared U.S. and with Canada are no longer shared. This is because of the new DST rules that are in effect for the U.S. and for Canada. When a computer that is set to Mexico Standard Time or to Mexico Standard Time 2 installs this update, the computer will be automatically set to the new time zone that is listed in the following table. However, this is not true for computers that are set to the GMT-08:00 time zone (Pacific Standard Time). If applicable, these computers must be manually set to the new Pacific Standard Time (Mexico) time zone.

MORE INFORMATION

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 "(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"
