Linux sets a software clock from the hrdware when it starts up. Some 
distributions (certainly Suse8.2) write the time back to the clock at 
shutdown. So you have a range of options to choose from. A quick fix would be 
to disable the write back at shutdown (/etc/rc.d/boot.clock on my Suse box), 
but if you really want to do it properly then read up on (man 2/8) adjtimex.

Thats more than just slippage. If it helps, I know of a Windows box which 
occasionally jumps forward 150 years causing the applications it runs to 
crash (so I'd be interested to find out why yours is doing this).
