Last week, when working on the East Coast, a different time zone than home, I was asked how I managed to keep track of things in the different time zones. Windows 7 has a great little feature to add multiple time zones to the clock.
1. Click the time in the lower right on the task bar and click “CHANGE DATE AND TIME SETTINGS”
2. In the DATE AND TIME dialog, go to the ADDITIONAL CLOCKS tab and setup 1 or 2 additional time zones and name them
3. Now the taskbar shows both (or all three) time zones
4. If you click on the time in the task bar, you now see clocks for both time zones active there as well
