   In mechanical clocks a gear train drives the hands; in electronic clocks the circuit produces pulses every second which drive a stepper motor and gear train, which move the hands. Digital clocks display the time in periodically changing digits on a digital display. A common misconception is that a digital clock is more accurate than an analog ...
