Timekeepers are officials who use a stopwatch to measure the amount of time that has passed during an event. They are responsible for keeping track of the time elapsed in a race, game, or other timed event. Timekeepers are often seen at sporting events, such as track and field, swimming, and cycling, but they can also be found at other events, such as music competitions and theatrical performances. Timekeepers are essential for ensuring that events run smoothly and accurately.
