Show multiple time zones in the system tray

If you’re an international traveller, or have family or business overseas, this one might come in handy, allowing you to display up to two extra clocks from the system tray.

1. Click on the time, then click on the Change date and time settings… link
2. Click on the Additional Clocks tab
3. Check one of the boxes that says Show this clock
4. Set the time zone and display name and click OK when done
5. Now when you click on the time, a second or third clock is shown, with the display name used as a label above it

World time is one click away.
