发明名称 Electronic timepiece and time difference correction method for an electronic timepiece
摘要 An electronic timepiece has a function for receiving satellite signals transmitted from positioning information satellites for capturable positioning information based on the received satellite signal and a positioning calculation unit that generates positioning information. A time information adjustment unit corrects the internal time information based on the time difference in the assumed positioning region when the time difference evaluation unit determines that the assumed positioning does not contain a time difference boundary. The positioning calculation unit reselects the specific number of positioning information satellites and continues the positioning calculation when the time difference evaluation unit determines that the assumed positioning region contains a time difference boundary. The reception unit terminates satellite signal reception when the time difference evaluation unit determines that the assumed positioning region does not contain a time difference boundary.
