I wanted to send out a quick note about a change that you might notice this weekend.  Daylight Saving Time (DST) will start on March 11, 2007, which is three weeks earlier than usual, and it will end on November 4, 2007, which is one week later than usual. This results in a new DST period that is four weeks longer than in previous years. Unless certain updates are applied to your computer, the time zone settings for your computer's system clock may be incorrect during this four-week period. In particular, you must make sure that both your Windows operating system and your calendar programs are updated.

Microsoft has created a tool to see if your computer is affected by this based on the operating system you are using.  You can get to this tool by going to http://support.microsoft.com/gp/cp_dst and following the instructions toward the bottom of the screen.   There you will see a Daylight Saving Time Update Guide which will ask you a couple of questions to determine if you need to download anything at all and it will prompt you to download a fix for this issue if it determines you need one.
