In basketball, a shot clock is used to ensure teams attempt a shot within a certain time frame. The shot clock typically lasts 24 seconds in the NBA and FIBA games, and 30 seconds in NCAA games. If a team does not attempt a shot within that time limit, it results in a shot clock violation, and the ball is turned over to the opposing team.
The singular possessive form of the noun "clock" is "clock's."
The pendulum of a clock is the long weighted bar that swings back and forth in the case below the clock. It was discovered several hundred years ago that the time it takes for one swing of a particular pendulum is constant, no matter how big or small the swing is. It can, therefore, be used to measure time.
The past tense of "wind the clock" is "wound the clock."
The clock period is the time duration of one clock cycle. For a clock frequency of 1 GHz (1 billion hertz), the clock period would be 1 nanosecond (1/1,000,000,000 seconds).
