摘要：A time adjustment device has a reception unit (40) that receives a satellite signaltransmitted from a positioning information satellite, a time information generating unit(38) that generates internal time information, and a time information adjustment unit (44)that adjusts the internal time information. The satellite signal contains satellite timeinformation that is kept by the positioning information satellite. The reception unitincludes a signal level acquisition means that searches for positioning informationsatellites and acquires the signal level of the satellite signal transmitted from eachpositioning information satellite, a reception satellite selection means that selects apositioning information satellite based on the acquired signal level, and a satellite timeinformation acquisition means that receives the satellite signal transmitted from thepositioning information satellite selected by the reception satellite selection means, andacquires the satellite time information contained in the satellite signal. The time

information adjustment unit adjusts the internal time information based on the acquiredsatellite time information when the satellite time information acquisition means hasacquired the satellite time information.
