Time adjustment device, timekeeping device with a time adjustment device, and time adjustment method

Abstract

A timepiece can acquire time information in a short time, reduce power consumption, and display the correct time. A timepiece comprises a receiver to receive a satellite signal, and a time information generator to generate internal time information. The receiver runs a first reception process that acquires first information including week information from the satellite signal, a second reception process that acquires second information including leap second information from the satellite signal, or a third reception process that acquires third information including hour, minute and second information from the satellite signal. In the first reception timing, after the internal time information is initialized, the receiver runs the first reception process and runs the second reception process after running the first. In a next reception timing, after the first reception timing, the receiver runs the third reception process if the first and second information are acquired in the first reception timing.
