Note: "A time clock, sometimes known as a clock card machine or punch clock or time recorder, is a device that records start and end times for hourly employees (or those on flexi-time) at a place of business.

In mechanical time clocks, this was accomplished by inserting a heavy paper card, called a time card, into a slot on the time clock. When the time card hit a contact at the rear of the slot, the machine would print day and time information (a timestamp) on the card. One or more time cards could serve as a timesheet or provide the data to fill one. This allowed a timekeeper to have an official record of the hours an employee worked to calculate the pay owed an employee." - (en.wikipedia.org 14.07.2022)
