Clock, Mechanical, Digital, & Atomic

A clock is a mechanical or electrical device other than a watch for displaying time. A clock is a machine in which a device that performs regular movements in equal intervals of time is linked to a counting mechanism that records the number of movements. All clocks, of whatever form—whether 12-hour clocks or 24-hour clocks—are made on this principle.
