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 correcting displaying the hour on an electronic watch. The location, such as a city, is also displayed so that the traveller is apprised of both the correct time and present location automatically.
