A world clock site is a tool  used to  show, keep, and co-ordinate time. The world clock map is derived ultimately (via Dutch, Northern French, and Medieval Latin) from the Celtic words clagan and clocca meaning "bell". A silent tool missing such a mechanism has traditionally been known as a timepiece. Generally usage today a "clock" refers to any device for evaluating  and displaying the time zones map. Watches and other timepieces that can be carried on one's person are often distinguished from clocks.
