摘要
An analog clock with a contiguous digital display is driven by radio signals from a WWVB or other time keeping radio station. To avoid using magnetic or optical feedback of the position of the hands of the analog clock if an erroneous time is shown (for example because of replacing the battery), the user of the clock physically resets the digital display to the analog setting (which of course is erroneous). Then an associated microprocessor speeds up or slows down the running of the analog clock until a match is made to the actual radio time.
