Abstract:
An electronic timepiece that receives satellite signals transmitted from positioning information satellites includes: a satellite signal reception unit that receives satellite signal(s); a satellite capturing unit that executes a process of capturing at least one of the satellites within a capture time based on the satellite signal(s) received by the reception unit; a time adjustment information generating unit that acquires satellite information from the satellite signal(s) transmitted from the captured satellite(s), and generates time adjustment information based on the satellite information; a time information adjustment unit that adjusts internal time information based on the time adjustment information; and a time information display unit that displays the internal time information. The capture time is from the start of reception of the satellite signal(s) to capture of at least one satellite, and if no satellite is captured within this time period, the satellite capturing unit stops reception of the satellite signal(s).
