Windows Advances date incorrectly

[Mike Williams]

I have been having a problem where I find the system clock advanced by 1
day. This seems to happen 1 to 2 times per week. I have browsed all of the
system files and found no indications of changes being made to the clock.
Any suggestions would be greatly appreciated.

It's possible that it is being set via the network, possibly by
synching to a machine that's off by a day. I don't know what you mean
by "all of the system files", but if the Windows time service sets the
clock, you should see an entry in the system log in the Event Viewer:
(Right-click "My Computer"->manage->system tools->event viewer->system)
-- look or filter for "W32Time" in the Source Column.
From a command prompt, you can enter the command:
net time /setsntp:<sntp-time-server-ip-address>
to have your time set from a known good network sntp server.
It's possible you have a 3rd party program running that changes the
time, too. Also make sure the correct Time Zone for your area is
specified in the Date/Time control panel.

HTH,
