What is Chess Clock?

A chess clock is a type of clock that consists of two adjacent timekeeping devices with buttons. It's used in two-player games where the players move in turn, such as chess. The purpose of the chess clock is to keep track of the total time each player takes for their own moves, and ensures that neither player overly delays the game. The clock is paused after a player completes their move, thereby stopping their allotted time from depleting, and starts the timing for the opposing player.
