摘要
A radio signal bearing time data is detected by an antenna (18) and then amplified (19,21) and filtered (22). The signal is then demodulated (23) and formed (24). A standard strength reference signal is produced by a generator (25) and this is compared with the incoming signal by a comparator (29). If the signal is satisfactory a processing and control unit (17) which may operate automatically or under manual control (28) drives a step by step motor (15) to correct the clock hands (12,13,14). If not the second hand is made to advance in an unusual and distinctive manner.
