Abstract
An information retrieval system and method for determining the location of a traveller based upon a comparison between broadcast radiowave frequencies at the location and a table of locations for radio stations which broadcast at those radiowave frequencies. By determining the location, the offset hour for the time zone where the radio station is located may be obtained for correctly displaying the hour on an analog watch. When the watch is moved to a different time zone, the hands are accelerated, forward or backward, until they indicate the local time. The location, such as a city, can also be displayed so that the traveller is apprised of both the correct time and present location automatically.
