Extended Daylight Saving Time, SBS 2003, and You

The U.S. Energy Policy Act of 2005, passed by the U.S. Congress July, 2005, extended Daylight Saving Time (DST) in the U.S. by approximately four weeks. As a result, beginning in 2007, DST will start three weeks earlier on March 11, 2007, and end one week later on November 4, 2007, resulting in a new DST period that is four weeks longer than previously observed. These four weeks are referred to in this article as the "extended DST period".

Unless certain updates are applied to your computer, it is possible that the time zone settings for your computer's system clock may be incorrect during this four week period. This depends on where you live and which time zone you have selected.

Before you Begin:

Rapid succession of steps is important: It is preferable to run the Outlook Time Zone Update tool or its Exchange counterpart as soon as possible after the time that the Windows operating system time zone patches are applied to all machines. If meetings between March 11, 2007 and April 1, 2007 are scheduled after the operating system patches are applied but before the tool is run, they will erroneously be moved one hour earlier. To correct such calendar items, organizers should manually update such meetings to ensure they are scheduled accurately for themselves and all invitees.

Updates for SBS 2003

Install the Windows OS update to the SBS 2003 server and all Windows 2003 servers on the network.(High-priority update on Windows Update and Microsoft Update on 2/13/2007).

Install the Windows OS update to all Windows XP/2003 clients on the network. (High-priority update on Windows Update and Microsoft Update on 2/13/2007).

3. If you have any Mac clients with Entourage 2004, install the Entourage 2004 update. See Microsoft Office 2004 for Mac 11.3.3 Update.

[update from previous post] If you have an environment where the following conditions are true:

Users rely heavily on Outlook Web Access
Users create lots of recurring calendar items in OWA.

Please consider uninstalling update KB 926666 (applies only to Exchange 2003 SP 2) or KB 931978 (applies only to Exchange 2003 SP 1) from Add or Remove Programs prior to running the Outlook or Exchange Time Zone Data Update Tools (in Step 5). Then reinstall the appropriate update (in Step 6) once you have run the tools.

Recurring calendar items in Outlook Web Access will read from the system time of the Windows system clock on the Exchange Server computer. So at the time that you run the update tools, they will not correctly detect the time zone or time zone rules under which the recurring item was created. If users in your environment create many calendar items using Outlook Web Access and you have already updated your calendars, we recommend advising users to carefully review their calendars and to manually correct any items that might not reflect the correct time during the extended DST period.

5. Run the Outlook and/or Exchange Calendar Update tool(s) to adjust calendar appointments in the extended DST period. This is not required. You may optionally have users manually adjust their appointments in the extended DST period.
