Vista Clock

Hi, Brian

You might try the following fix from Torgeir Bakken (MVP)
This will re-synchronize your clock.

First, click the clock on the task bar for the right time,

right click cmd.exe hit Enter and select Run as Administrator,

Type the following:
CD\ hit Enter to drop into the root directory,
net stop w32time hit Enter,
w32tm /unregister hit Enter, (ignore any error messages)
w32time /register hit Enter,
net start w32time hit Enter.

Good Luck,
