Greetz all. In case you didn't know, the US's Daylight Savings Time changes this year. It used to start on the first Sunday of April, but now it will be starting the 2nd Sunday of March (March 11 this year). It will also now be ending the first Sunday of November (Nov 4 this year) instead of Last Sunday of October like it was before.
Your computers automatically adjust to DST, but it was based on the 'old rule'. People running Vista have nothing to worry about, but anyone XP and older will have to patch. I'm not sure about Mac or other OSes, but I'm sure they'll have something available.
Windows users, read up here on how to get yourself sorted out.
