ABSTRACT:
A time adjustment device has a reception unit that receives a satellite signal transmitted from a positioning information satellite, a time information generating unit that generates internal time information, and a time information adjustment unit that adjusts the internal time information. The satellite signal contains satellite time information that is kept by the positioning information satellite. The reception unit includes a signal level acquisition unit that searches for positioning information satellites and acquires the signal level of the satellite signal transmitted from each positioning information satellite, a reception satellite selection unit that selects a positioning information satellite based on the acquired signal level, and a satellite time information acquisition unit that receives the satellite signal transmitted from the positioning information satellite selected by the reception satellite selection unit, and acquires the satellite time information contained in the satellite signal. The time information adjustment unit adjusts the internal time information based on the acquired satellite time information when the satellite time information acquisition unit has acquired the satellite time information.
