The problem is that your Linux install is assuming the system hardware
clock is in GMT while XP is assuming it is in your local timezone. The
solution is to set the Linux side to assume your system hardware clock is
in your local timezone.
I'm not in front of my FC6 install at the moment so I can't be sure of the
details, but it should be under 'Applications' -> 'System Settings' ->
'Date & Time' in the 'Timezone' tab of the dialog. Uncheck 'System Clock
uses UTC'. That should put a stop to the clock changes.
