926666 Update for daylight saving time changes in 2007 for Exchange 2003 Service Pack 2
Note Microsoft Exchange Server 2007 does not require an update to correctly reference DST changes.
In the spring of 2007, the start dates and the end dates for DST in Newfoundland will change to comply with the Energy Policy Act of 2005. The dates will change as follows:
|Start date||Second Sunday in March, 12:01 A.M.||First Sunday in April, 2:00 A.M.|
|End date||First Sunday in November, 12:01 A.M.||Last Sunday in October, 2:00 A.M.|
A time zone update for DST that will address this issue in Exchange Server 2003 SP2 is now available.
Before you apply this update for Microsoft Exchange Server 2003, you must install Exchange Server 2003 SP2 and the time zone update for Microsoft Windows.

Why the update is required for Exchange Server
Microsoft calendar software, such as Outlook, depends on the operating system's 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 were 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
What to consider if you are running Exchange Server 2003 Service Pack 1 (SP1)
This update cannot be applied if you are using Exchange Server 2003 SP1.
