If you didn't realize it. The US Government has made a change to the way Daylight Savings works for 2007. Here is some FAQ from the SBS team:
Q: I’ve heard something about Daylight Savings Time updates or DST 2007? what do I need to know?
A: 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). Updates to several Microsoft products are required to fully implement this change on an SBS Server. Full details on the updates required are available at http://www.microsoft.com/windows/timezone/dst2007.mspx At this time there are no unique SBS 2003 updates required, although there are updates required to several SBS components (windows Server, Exchange Server, Outlook 2003, Windows SharePoint Services). Please follow the detailed instructions at http://www.microsoft.com/windows/timezone/dst2007.mspx.
This applies to all versions of SBS, That's SBS RTM, SBS SP1, SBS R2, etc.
Hopefully this will make it so I see more sunlight during the winter months... oh wait, that's the rain and cloud cover, never mind.
