Unwanted one minute time adjustments

Hi, I have a situation in which it seems my Windows 2000
and 2003 machines sync the software clock back to the
hardware clock value once it is close to a minute ahead of
the hardware clock. I have removed all time syncing
software and made sure net time does not have a server to
sync to. Also, I have set the hardware clock 15:00 minutes
ahead and the software clock is constantly syncing itself
but always staying 15 minutes ahead of real time. (this
should rule out any 3rd party syncing software). This only
happens on machines that undergo heavy load. I've only
found two articles that briefly mention this behavior, but
with no mechanism to turn this behavior off.




I need this to stop. Any help appreciated.
 
Disconnect your machine from the network and from the
Internet. Does this behaviour still occur?

That is a great idea, and I really wish I had that luxury.
Unfortunately I cannot take these systems offline for that long. They
run critical tests that have to be published. I'm hoping that by
setting the hardware clock ahead by 15 minutes and showing that the
time always ends up under 60 seconds from the hardware clock, I am
ruling out any external syncing.

I was finally able to do this. The machine still back syncs with the
ethernet cable unplugged.

If this is so then you have some task or service that plays
games with your system time. Download one of these free
tools and examine very carefully what's running on your
machine. You could also run msconfig.exe from a WinXP
machine to enable/disable your startup tasks.
