What’s all the fuss around Daylight Saving Time (DST) changes in 2007?
Well, in August of 2005 the United States Congress passed the Energy Policy Act, which changes the dates of both the start and end of daylight saving time (DST). When this law goes into effect in 2007, DST 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) than what had traditionally occurred.
What countries will be impacted by this change?
All of the United States (except Arizona, Hawaii, Puerto Rico, the U.S. Virgin Islands, and American Samoa) and Canada.
What Microsoft products are affected by the DST legislation?
Windows SharePoint Services
Microsoft Exchange Server
Microsoft Office Outlook
Microsoft Dynamics CRM
Where can I get additional information?
Where can I download the fix for Exchange Server 2003 SP2?
Update for Daylight Saving Time changes in 2007 for Exchange 2003 (KB 926666). This update includes the changes for the United States DST change for the components affected in Microsoft Exchange. It also includes changes for the time zones in Canada (except Newfoundland) which will make the same change to their DST transition dates from 2007.
Additionally this update includes changes to time zone behavior and DST settings that have taken place since Exchange Server 2003 was originally released. These changes were previously released as individual updates and documented in articles in the Microsoft Knowledge Base.
