    This is normal - it is caused by Mac OS X and Windows interpreting the system time stored in the hardware differently. On UNIX systems, such as Mac OS X, the system time is stored as UTC, then the time zone offset is applied by software to get the displayed time. On Windows, the time zone offset is pre-added to the UTC hardware time. This results in things like Mac OS X saying the time is 8:30 PM (Eastern Daylight Time in the USA) and Windows thinking it's really 4:30 PM (EDT = UTC - 4 hours).

    This is why Apple created the Apple Time Service to keep Mac OS X and Windows in sync when using Boot Camp.

    Do you have the Boot Camp drivers installed? If not, install them. They'll make your Windows experience much more friendly.
