Rewind back to 1999...  As the year progressed, did you stock up on food, water and other "provisions"?  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.

Why didn't we just abolish the darn thing?

Anyway, if you are concerned about the impact of the time change on your software and computer systems, see http://support.microsoft.com/gp/dst_overview for a consolidated view of the changes in Microsoft software.

[UPDATE]  See http://office.microsoft.com/en-us/outlook/HA102086071033.aspx for information on Office.

  • One of my domain controllers is also our timeserver which syncs to NIST at Boulder.  Every other machine in the building syncs to that via Active Directory..  I'm thinking the DST change will be a non-issue... right?

  • I know as an application programmer, anything that came along and effected our business rules was a big deal.  Date and time are important for instance in calculating health benefits, interest rates, etc.

    So while it might be a non-issue in the OS or an application like Outlook, it's the custom applications and systems where the real impact is.
