I've set up a dual boot betwix Windows 7 RC and Ubuntu. Every time I boot into Windows after booting into Ubuntu I get the wrong time which is kind of annoying. I have to resync online with Windows to get the right time, but since I can change what format
Ubuntu saves its time as I just want to know what format Windows uses. Is it UTC? Is it local? Is it magic?
Any help would be appreciated.

Windows expects the BIOS clock to be set to local time, and modifies it when you switch time zones. Linux generally expects the system clock to be set to UTC, and translates it to local time whenever you display it. Just a difference in defaults.
There is a hack to make Windows run the system clock in UTC, but you can change /etc/default/rcS on your Ubuntu drive to say UTC=no and be supported by both OSes, I believe.
