<p>PURPOSE:To compensate the clock error of clock devices in respective units correctly by calculating the difference of time data transmitted from respective units and time data which a reference time device shows, and permitting respective units to add the difference to the present time so as to set it in its self clock device. CONSTITUTION:A calculation/transmission means 6 calculates the difference between the time A included in a request and a time B which the reference clock device 5 outputs, and returns it to an electronic computer 1. A request means 3 automatically issues the compensation request of the time, generates the error based on the clock time of the reference clock device 5, and a resetting means 4 executes resetting by adding the error to the time when the error is reset. Thus, a procedure from supervising the time to resetting is fully automatically executed without a manual operation, and therefore the accurate time can be compensated.</p> |
