Time Adjustment Device, Timekeeping Device with a Time Adjustment Device, and a Time Adjustment Method

A timekeeping device with a time adjustment device comprising:

• a reception unit that receives a satellite signal transmitted from a positioning information satellite;
• a time information generating unit that generates time information;
• a generated time information storage unit that stores the time information generated by the time information generating unit as generated time information;
• and
• a starting information generating unit that generates information before the beginning of a specific unit of the satellite signal that is transmitted in specific units from the positioning information satellite as before-starting information based on the generated time information;
• wherein the reception unit has a starting unit that starts searching for the positioning information satellite at a predetermined timing based on the before-starting information, and
• a stopping unit that detects the specific unit of the satellite signal and stops searching for the positioning information satellite;
• and
• the generated time information is corrected at the timing when the reception unit stops.

A time adjustment method comprising:

• a time information generating step of generating time information;
• a generated time information storage step of storing the time information generated by the time information generating step as generated time information;
• a starting information generating step of generating information before the beginning of a specific unit of the satellite signal that is transmitted in specific units from a positioning information satellite as before-starting information based on the generated time information;
• a reception step including a starting step that starts searching for a positioning information satellite at a predetermined timing based on the before-starting information, and
• a stopping step that detects the specific unit of the satellite signal and stops searching for the positioning information satellite;
• and
• a step of correcting the generated time information at the timing when the stopping step of the reception step stops reception.
