Digital clock

This article is about the appliance. For timing reference for digital audio, see Word clock.

A digital clock displays the time digitally (i.e. in numerals or other symbols), as opposed to an analogue clock.

Digital clocks are often associated with electronic drives, but the "digital" description refers only to the display, not to the drive mechanism. (Both analogue and digital clocks can be driven either mechanically or electronically, but "clockwork" mechanisms with digital displays are rare.)
