Some of you may already know of the upcoming changes in Daylight Savings Time, and their impact on time-related software, and updates available from Microsoft. In case you are not, I would like to bring this to your attention.
One of the key provisions of the Energy Policy Act of 2005 extends Daylight Saving Time (DST) by approximately four weeks. In compliance with this provision, beginning in 2007 DST dates in the United States 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).
Details of the updates for Microsoft Windows and affected Microsoft applications, how customers and partners can acquire them and when they will be available can be found on the Microsoft website at http://www.microsoft.com/windows/timezone/dst2007.mspx. Corresponding Technical Knowledge Base Articles can be linked to from this website as well.
Microsoft is providing the Time Zone updates at no-cost for customers and partners on Windows platforms that are covered by mainstream support. Customers or partners who have an Extended Hotfix Support Agreement can request a hotfix for products in Extended Support.
