[ubuntu-uk] Odd behaviour of system clock

[I C McNab]

I recently set up a dual boot system with Fiesty and WinXP on separate 
drives.  (Previously, I've used various versions of Ubuntu as the only 
OS on a laptop and a desktop.)  I've just noticed on the dual boot 
system that when I restart XP after using Ubuntu the system clock 
appears to have lost an hour.  (I guess it could be resetting to GMT, 
and losing the BST adjustment.)  The Ubuntu clock is fine.

Has anyone had a similar experience?  Is there a fix - apart from 
manually resetting the time (or never using that other OS!)?
