Don't forget that Daylight Saving Time begins this weekend! Congress expanded DST in the Energy Policy Act of 2005, and we now "spring forward" on the second Sunday of March and "fall back" on the first Sunday of November. Of course if you live in Arizona or Hawaii, it doesn't affect you.
If you need to download an update for your computer (mine seems to have downloaded and installed the update automatically), here are some links.
