Claims

A receiving unit that receives a satellite signal transmitted from a position information satellite and obtains position information and time information included in the satellite signal;
A timekeeping section for measuring the internal time,
Block position information indicating the position of a plurality of blocks that divide the earth surface, and a storage unit that stores the time zone of each block in association with each other
A first information acquisition unit that causes the reception unit to receive the satellite signals transmitted from three or more position information satellites, and acquires position information and time information included in the satellite signals;
A time zone acquisition unit for acquiring, from the storage unit, the time zone associated with a block including the current location indicated by the position information acquired by the first information acquisition unit among the plurality of blocks;
A first local time calculation unit that calculates a local time based on the time zone acquired by the time zone acquisition unit and the time information acquired by the first information acquisition unit;
A first time correction unit for correcting the internal time based on the local time calculated by the first local time calculation unit;
A second information acquisition unit that causes the reception unit to receive the satellite signal transmitted from the one position information satellite, and acquires time information included in the satellite signal;
A second local time calculation unit that calculates a local time based on the time zone acquired by the time zone acquisition unit and the time information acquired by the second information acquisition unit;
