Display Multiple Clocks

If you're a frequent traveler or have friends or family in another time zone, you can set up Vista to display multiple clocks at once. Click on the clock in the Start bar, then click "Change date and time settings"¦," and then the Additional Clocks tab. Check the box next to "Show this clock" for each additional clock you want to add, then specify the time zone and display name for each clock. After you apply your changes by clicking OK, clicking on the clock in the Start bar will show you the clocks for every time zone you've selected.
