ABSTRACT:
In an electronic timepiece having a signal receiving function, the present time at a place where a user is located can be displayed without designating a regional name. The quasi-distance data between the satellites and the signal receiving point is calculated based upon the delay times of the signals transmitted from the satellites. The positional information about the signal receiving point is obtained from four quasi-distance data. Subsequently, this positional information is compared with the longitude/latitude data previously stored in ROM, to search a city located nearest this signal receiving point. Furthermore, a judgement is made whether or not the city located nearest the present receiving point is coincident with the city located nearest the preceding receiving point. If these cities are coincident with each other, then the present time of the city stored in the time counting register is directly displayed. If no coincidence is established, then the time counted by the time counting unit is corrected based upon the time difference data about the city located nearest the present signal receiving point, and also the corrected time is displayed in combination with the name of this city.
