87. How Do I Correct A Time Error In Windows XP

There are occasions when the Windows XP Time goes a little haywire. One minute the time is spot on, and the next the time has advanced or decreased by minutes or even hours. If manually adjusting the time via the Date and Time option in Control Panel is unsuccessful you may need to un-register the Windows time module and then re-register it. To do this proceed as follows.

Click the Start button.
From the Start menu select: All Programs>Accessories>Command Prompt.
in the Command Prompt window type: net stop w32time and press Enter.
Next type: w32tm /unregister and hit Enter again
Now type: w32tm /register and again hit Enter.
Now type: net start w32time and hit Enter again.
Finally close the Command prompt window.
