Abstract

A time display device (1) has location detecting means (5, 14, 15, 16) for detecting a location of the time display device (1), clocking means (21) for counting time and time adjusting means (17, 18, 19, 20) for adjusting the counted time of the clocking means (21) to match a local time of the location detected by the location detecting means (5, 14, 15, 16). The location detecting means (5, 14, 15, 16) acquires location information via a global positioning system (GPS) and the time adjusting means (17, 18, 19, 20) automatically computes the local time and adjusts the counted time of the time display device (1) to display the local time, so it is not necessary for the user to perform some operation to adjust the time of the time display device (1) to the local time.
