you just need to update your OS so it knows the new daylight savings time dates, as it did change... there is an update for windows that fixes it, if that's what you have.. Vista won't need it, but XP does if it's not done already.... today my computer ( Linux box ) booted up and had it was an hour behind what it should have been.. the OS is a fully updated version so I thought somthing was wrong.. then I rebooted and the time was right.. kinda weird.
