Time clock

Time clock is a machine or device that tracks how much time someone spends at work. It helps employers and employees keep track of how much time each person spends at work. Some time clocks even have buttons to use when you come to work and when you leave, so they know exactly when you are working. For example, if your job is to work 8 hours a day, the time clock will track the 8 hours and show the employer how much time you worked.
