<P>PROBLEM TO BE SOLVED: To provide a radio controlled clock capable of realizing the switching of proper processing in accordance with the radio wave conditions relating to the reception of radio wave or processing of time correction. <P>SOLUTION: The radio controlled clock 1 which performs time correction by receiving time code signal for every second synchronization point, by calculating the time variation amount of the reception timing of the signal wave form representing the second synchronization point (S12) switching the processing contents (e.g. reception frequency) (S23), and treating properly the wave reception and time correction, according to the radio wave condition. <P>COPYRIGHT: (C)2009,JPO&INPIT |
