A clock is an instrument used for measuring time, and is one of the oldest human inventions, predated by the sundial. It often consists of a face with numbers or lines from one through twelve, and an hour, minute, and sometimes second hand. Other clock faces may display the time digitally. Clocks may be freestanding, hung on the wall, or worn on the wrist as a watch.
