<p>A low cost remotely resettable wall clock (10) or the like is provided, which is driven by a conventional quartz oscillator system (14, 15), for example. On a once a day basis, a reset signal is received from a local broadcast station (11), which serves to reset the clock to a predetermined reset time, typically 02:00:00 am. The system includes means (22, 23) for automatic start-up of the clock without setting of the hands, eliminating the need for mechanical reset facilities. The control system includes means for automatically advancing or retarding the clock reset by one hour, to accommodate the beginning or the end of daylight savings time. The economical design of the clock system enables it to be suitable for household as well as commercial use.</p> |
