Windows will update both the hardware and software clocks with the
SetSystemTime function (IIRC), but NTP doesn't use that function in normal
operation - it alters the clock rate instead (as you know, of course).
As the OS functions have been bypassed, perhaps NTP on the Windows
platform should replace the functionality it has bypassed with an
occasional setting of the hardware clock? Perhaps this is true for other
operating systems as well?
