timekeepers
Those tracking hours
Timekeepers are people or devices that track time.
A timekeeper at a sporting event monitors how long play has lasted.
Watches, clocks, and stopwatches are timekeepers.
Someone who is a good timekeeper arrives punctually and meets deadlines: She's always been a reliable timekeeper.
