Important Updates are available on Windows Update and on Microsoft Update that enable Windows to correctly apply the changes for daylight saving time (DST) 2007 and later. After these updates are applied, Windows correctly calculates the current offsets from UTC time to local time on the computer when DST occurs. The offsets include the offsets for the base APIs and for the networking time-related APIs. You can visit the Microsoft Update Web site by visiting the following Microsoft Web site:

http://www.update.microsoft.com

For more information about the Automatic Updates feature in Windows, click the following article number to view the article in the Microsoft Knowledge Base:

294871 Description of the Automatic Updates feature in Windows

Important The update that is described in this Microsoft Knowledge Base article has been replaced by the update that is described in Microsoft Knowledge Base article 933360. To make sure that Microsoft Windows has the latest time zone data, install the update that is described in Microsoft Knowledge Base article 933360. For more information about the update that is described in Microsoft Knowledge Base article 933360, click the following article number to view the article in the Microsoft Knowledge Base:

933360 August 2007 cumulative time zone update for Microsoft Windows operating systems

Note You do not have to uninstall the update that is described in this Microsoft Knowledge Base article before you install the update that is described in Microsoft Knowledge Base article 933360.

Before you apply the 2007 cumulative time zone update for Windows operating systems, 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:

931667 How to address the daylight saving time changes in 2007 by using the Time Zone Data Update Tool for Microsoft Office Outlook



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 (2:00 A.M. on the second Sunday in March) and will end one week later (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 United States DST change. This time zone update will also include changes for other related DST changes, time zone behavior, and settings. Some of these changes will occur in 2007, and some have occurred since these versions of Windows were originally released. The update that this article describes also includes some changes that have previously been released as individual hotfixes. An example of this is the Sri Lanka change in time zone offset. This update will also include some changes that have been individually documented in Microsoft Knowledge Base articles.

These updated time zone definitions will also be included with Windows Vista.

For more information about Windows Vista, visit the following Microsoft Web site:

http://www.microsoft.com/windowsvista

Additional registry keys in Windows Vista
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. The additional registry keys are not used by versions of Windows earlier than Windows Vista. The information is provided for other programs that may use the information to predict or to compute future and past time zone information.
