An electronic timepiece includes a reception unit that receives satellite signals transmitted from positioning information satellites and acquires time information and positioning information, a time zone information storage unit that stores region data dividing geographical information containing time difference information into a plurality of regions, and time difference information contained in each region, a time difference information acquisition unit that extracts the region containing the positioning information acquired by the reception unit from the region data, and acquires the time difference information contained in that region, and a time calculation unit that calculates the current time based on the time difference information acquired by the time difference information acquisition unit and the time information acquired by the reception unit. The region data stored in the time zone information storage unit including region data dividing the geographical information into a plurality of regions, and region data further dividing each region that contains a plurality of time difference values into a plurality of regions. |
