Time adjustment device, timekeeping device with a time adjustment device, and a time adjustment method

摘要

A time adjustment device having a reception unit that receives a satellite signal transmitted from a positioning information satellite; a time information generating unit that generates time information; a generated time information storage unit that stores the time information generated by the time information generating unit as generated time information; and a starting information generating unit that generates information before the beginning of a specific unit of the satellite signal that is transmitted in specific units from the positioning information satellite as before-starting information based on the generated time information. The reception unit has a starting unit that starts searching for the positioning information satellite at a predetermined timing based on the before-starting information, and a stopping unit that detects the specific unit of the satellite signal and stops searching for the positioning information satellite. The generated time information is corrected at the timing when the reception unit stops.
