A "timekeeper" is a person or device responsible for measuring and recording time. In various settings, such as sports events or workplaces, timekeepers ensure that activities are conducted within specific time limits. They may use tools like clocks, stopwatches, or timers to track durations accurately. In the context of sports, a timekeeper plays a crucial role in maintaining fairness and order during competitions. For example, in track and field events, the timekeeper records the finishing times of athletes, while in swimming, they monitor lap times. Their precise measurements help determine winners and ensure adherence to rules.
