time-keeping
Measuring passing moments
Time-keeping is the practice of tracking and recording time, whether for punctuality, work hours, or athletic performance.
In employment contexts, time-keeping systems monitor when workers clock in and out: The company switched to digital time-keeping.
In music, time-keeping refers to maintaining steady rhythm: The drummer's time-keeping was impeccable.
Someone's time-keeping is their habit of being punctual or late: His time-keeping leaves much to be desired.
