Abstract:
     In time of travel procedure, the receiving circuit in electric wave clock decodes time signal received. Then, the decoded signal is transferred to a microprocessor. Processed by the microprocessor, the signal is transferred to step motor to make time display act to carry out dynamic time correction. In dynamic time correction, program K built in the microprocessor commands the step motor to move in advance or lag of a period of time T relative to sec. head of memorized time inside microprocessor, which controls step motor. Procedure of dynamic time correction is carried out in each N time period, where N is as 1 - 8 hours. The invention eliminates interference, which is generated by movement of the step motor, on coded time signal so as to make dynamic time correction more accuracy and effective.
