Starting next year daylight savings time change will move… and for those with Windows 2000 machines, that time change to standard/daylight won't be automatic. Why? Because Window 2000 won't get a patch that Windows XP machines will get that will automatically move that daylight savings to March from being April.
You can actually test the patch needed for 2007 now by downloading it here:
A test version of a time zone update for 2007 is now available for computers that are running Microsoft Windows Server 2003 and Microsoft Windows XP. In the spring of 2007, the start dates and the end dates for DST in the United States will change to comply with the Energy Policy Act of 2005. The dates will change as follows:
||DST starts on the second Sunday in March at 2:00 A.M. Therefore, DST in 2007 starts three weeks earlier than DST in 2006.
||DST ends on the first Sunday in November at 2:00 A.M. Therefore, DST ends one week later than in prior years.
The Windows updates are currently planned to be available for production deployment for all customer starting in mid-November 2006 through Microsoft Download Center. The update will be available via Windows Update, Automatic Update, and WSUS starting on December 12, 2006. Updates will be posted to this site as the final deployment date approaches.
Now then.. make sure you watch OEM machines, the daylight savings box and Outlook meeting times. I have been nailed several times with machines that end up not flipping to standard time and instead stay on daylight until I 'recheck' the box. If I don't double check this, I'll end up with someone's Outlook booking appointments off by an hour.
