Please nothe that the Windows multimedia timers are not necessarily used
only by multimedia programs. Any other program could do so.

Are you running Dell Poweredge servers? There's currently another thread in
the NG with time sync problems on those.

I've got a little tool which runs in the command line and reports what's
going on with Windows time synchronization:

It does not modify the Windows system time in any way, but you can run it
with a command line parameter which let's the program modify the Windows MM
timers while it is running. Since the system time only jumps back and forth
if the MM timers are set high and back low, keeping the log_adj program
running with the -m parameter in a command line window should make it
settle, if it's due to the MM timers.
