I have a Windows 2000 Professional workstation at a clients' site that is doing something I've never seen before. When I start the computer and go into CMOS, the correct date and time are displayed. Once Windows starts, however, the clock starts running (forward) wildly. If you click it up you see the second hand spinning, it takes about 2 seconds for each minute to pass. I tried stopping the Windows Time service, no joy. This machine is at a law office and correct time-stamping on emails and other documents is crucial.
