Electronic time clock. A time clock, sometimes known as a clock card machine, 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
Devices and methods for keeping time have gradually improved through a series of new inventions, starting with measuring time by continuous processes, such as the flow of liquid in water clocks, to mechanical clocks, and eventually repetitive, oscillatory processes, such as the swing of pendulums. Oscillating timekeepers are used in modern ...
A talking clock (also called a speaking clock and an auditory clock) is a timekeeping device that presents the time as sounds. It may present the time solely as sounds, such as a phone-based time service (see " Speaking clock ") or a clock for the visually impaired, or may have a sound feature in addition to an analog or digital face.
A reference clock may refer to the following: A master clock used as a timekeeping standard to regulate or compare the accuracy of other clocks In electronics and computing, the clock signal used to synchronise and schedule operations
The Waltham Watch Company, also known as the American Waltham Watch Co. and the American Watch Co., was a company that produced about 40 million watches, clocks, speedometers, compasses, time delay fuses, and other precision instruments in the United States of America between 1850 and 1957.
The paper disk or tape had the times pre-printed and the key impressed the key number on the corresponding time. After the shift (or a specified time period, up to 96 hours in the case of the Detex Guardsman clocks), an authorized person (usually a supervisor), would unlock the watchclock and retrieve the disk or tape and insert a new one.
A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. The advantage of a pendulum for timekeeping is that it is an approximate harmonic oscillator: It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates.
