Add additional clocks to the taskbar in Windows 7

In Windows 7, by default the time is displayed in the right part of the taskbar and you have the local time displayed in the taskbar clock. You can have two more clocks to display time from other time zones. Once you setup the additional clocks, you have to hover the mouse or click on the taskbar clock to view them. To add the additional clocks, perform the following:
1. Right-click on the taskbar clock and click on Adjust date/time.
2. From the Date and Time dialog box, click on the Additional Clocks tab.
3. For each clock, click to place a check mark beside Show this clock. Select the time zone from the Select time zone: drop-down box. Enter the name for the time zone in the Enter display name: field (Upto 15 characters are allowed in the Enter display name: field).
4. Click Apply and then click OK.
