摘要：
A time adjustment device has a reception unit that receives satellite signals transmitted from a positioning information satellite; a satellite signal processing unit that processes the satellite signal received by the reception unit and acquires at least satellite time information; a timekeeping unit that keeps time internally; and a time information adjustment unit that adjusts the internal time based on the satellite time information; wherein the reception unit and the satellite signal processing unit operate alternatively.
