INTRODUCTION
An update for daylight saving time (DST) changes in 2007 is now available for computers that are running Microsoft Exchange Server 2003 Service Pack 2 (SP2).
Note Microsoft Exchange Server 2007 does not require a patch to correctly reference DST changes.
MORE INFORMATION
Update information
In the spring of 2007, the start dates and the end dates for daylight saving time (DST) in the United States will change to comply with the Energy Policy Act of 2005. The dates will change as follows:
DST | In 2007 | In previous years |
---|---|---|
Start date | Second Sunday in March, 2:00 A.M. | First Sunday in April, 2:00 A.M. |
End date | First Sunday in November, 2:00 A.M. | Last Sunday in October, 2:00 A.M. |
A time zone update for DST that will address this issue for Microsoft Exchange Server 2003 is now available. This update includes the following:
- The new 2007 DST start dates and end dates for the United States.
- Changes to DST and time zone settings that will occur in Canada in 2007 (except in Newfoundland).
- Changes to DST and time zone settings that have occurred since the products in the "Applies to" section were originally released. For example, this update includes some changes that were previously released as individual updates and documented in articles in the Microsoft Knowledge Base.
Note This update is cumulative. Therefore, if you have not yet applied either of the security updates that are described in the following security bulletins, you may have to change the Send As permissions on your mobile device to make sure that the mobile device continues to function as you expect.
- MS06-019 (Store.exe version 6.5.7233.69 or a later version of Store.exe)
- MS06-029 (Store.exe version 6.5.7650.28 or a later version of Store.exe)

Why is the update required for Exchange?
Microsoft calendar software such as Outlook depends on the operating system time zone information to display time information. However, Collaboration Data Objects (CDO)-based programs such as Outlook Web Access depend on separate internal time zone tables. This update modifies these internal time zone tables to match the changes in time zone settings.
Without this update, calendar items in CDO-based programs and in Outlook Web Access will operate as if standard time is in effect during the extra weeks of daylight saving time. For example, without this update CDO-based programs will operate in standard time during the following periods in 2007:
- March 11, 2007 through April 1, 2007
- October 28, 2007 through November 4, 2007
