1. An electronic device, comprising:
a clocking unit which counts a date and time; a receiving unit which receives a transmitted radio wave from a positioning satellite; a reception control unit which controls a reception period by the receiving unit; and a date and time obtaining unit which obtains a date and time from the received transmitted radio wave, wherein among first date and time information of a first time unit transmitted from the positioning satellite and second date and time information of a second time unit which has a unit width larger than a unit width of the first time unit, the reception control unit makes the receiving unit receive only the first date and time information, and the date and time obtaining unit includes:
a date and time calculation unit which, on the basis of internal date and time information of the second time unit calculated from the date and time of the clocking unit and the first date and time information received by the receiving unit, calculates a date and time within a range according to the internal date and time information; anda date and time correction unit which corrects the calculated date and time on the basis of a difference between the date and time calculated by the date and time calculation unit and the date and time counted by the clocking unit.
