ABSTRACT:
A time adjustment device having a time information generating unit that produces time information and outputs the generated time information; a reception unit that receives satellite signals transmitted sequentially from a positioning information satellite in subframe information units where a plurality of subframe information units each containing satellite-time-related information and at least one subframe information unit containing satellite health information is a unit, the satellite-time-related information is the time-related information of the positioning information satellite, and the satellite health information denotes an operating condition of the positioning information satellite; an external input unit that outputs command information instructing the reception unit to receive in response to external input; a reception timing configuration unit that sets the start time of reception by the reception unit so that the satellite signal is received immediately or at a predetermined timing based on command information from the external input unit; and a time adjustment information storage unit that stores the satellite-time-related information of the satellite signal received by the reception unit as time adjustment information. The generated time information is corrected based on the time adjustment information, and reception by the reception unit starts when the start timing comes.
