timekeeping systems
Calendars and clocks
Timekeeping systems are methods and devices for measuring and recording the passage of time.
These range from ancient sundials and water clocks to modern atomic clocks and digital networks.
In workplaces, timekeeping systems track employee hours: The new timekeeping system requires workers to clock in with fingerprint scanners.
Broader systems include calendars and time zones that coordinate human activity across regions.
