The Cog VM (which it seemed Jimmie was using) uses a clock 
(sqWin32Heartbeat.c) initialized with
GetSystemTimeAsFileTime and timeGetTime
then adds an offset based on current timeGetTime (reinitialization 
happens at rollovers)

I can't see any mention of drift in the Microsoft documentation of 
timeGetTime, but I guess there must be some?

Cheers,
Henry
