I see. There's no reason we should be computing against the full value of the
count; since we're only looking for the microsecond portion we should have
stripped off everything greater. (E.g., count.QuadPart %= cFreq.QuadPart).
I'll have to play with this code a bit more, there's probably a better way to
isolate the microseconds.
PS: I guess that means your Windows machine had an uptime of several days.
Quite impressive, for Windows... ;)
