<p>PURPOSE:To eliminate a wrong time indication and a time adjustment by making a counter step forwardly everytime detecting coincidence of presumed time data with time data received thereafter, and by judging and outputting the received time data corresponding to a time when counted value of the counter becomes larger than a specific value, as correct time data. CONSTITUTION:Just when one time data is received, a timer 22 starts, a time data which is to be received thereafter, is presumed from a counted value of the timer 22 and the one time data, and the presumed time data and the aforementioned time data which is to be received thereafter, are compared by a comparator measure 23. A counting measure 19 steps forwardly everytime when the comparison result coincides, and the received time data corresponding to a time when the counted value of the counting measure 19 becomes larger than a specific value, is output as a correct time data.</p> |
