time-keepers
Those tracking duration
Time-keepers are people or devices that track the passage of time.
In sports and competitions, time-keepers monitor elapsed time and enforce time limits: The time-keepers signaled the end of the round.
A watch or clock that keeps time accurately is a good time-keeper.
The hyphenated form is less common than the solid compound timekeeper.
