Clock is an instrument used to indicate, keep, and co-ordinate time. In general usage today a “clock” refers to any device for measuring and displaying the time. The clock is one of the oldest human inventions, meeting the need to consistently measure intervals of time shorter than the natural units: the day; the lunar month; and the year. Devices operating on several different physical processes have been used over the millennia, culminating in the clocks of today. — Wikipedia
