How do I use the World clock on my Nokia phone?

To set the phone to show the time in other locations, scroll right to World clock. To add a location, select Options > Add location.

To set your current location, scroll to a location, and select Options > Set as current location. The location is displayed in the clock main view, and the time in your phone is changed according to the location selected. Check that the time is correct and matches your time zone.
