World Clock
World Clock displays the day and time in your home city and in two other cities around the globe. Whether you’re travelling or at home, it’s easy to keep track of the best time to reach your business associates, friends, and family in far away places.
Setting your home city
The home city serves as a point of reference for your other city selections. The home city time reflects the current system time. The information displayed for the other cities is based on the day and time in your home city.
If the Enable Local Network Time box is checked in your Date & Time Preferences, Cingular Wireless’s network automatically sets the time and updates it when you travel.
