Crazy Clock

Hi, I just installed Windows XP using boot camp (on leopard) and I think it made the clock go crazy. Before I installed XP it worked fine. Now it is 6 hours off. I have it set to pick up the time automatically and it is in the right time zone. I set it manually but every time I reboot in Xp and then back into OS X its off again. The clock is set right in XP however. Stupid Window's always causing trouble! Any help will be greatly appreciated.
