A clock generator is an electronic oscillator that produces a clock signal for use in synchronizing a circuit's operation. The output clock signal can range from a simple symmetrical square wave to more complex arrangements. The basic parts that all clock generators share are a resonant circuit and an amplifier.
Counting timers used in modern computers provide similar features at lower precision, and may trace their requirements to this type of clock. (e.g. in the PDP-8, the mains-based clock, model DK8EA, came first, and was later followed by a crystal-based clock, DK8EC.) A software-based clock must be set each time its computer is turned on.
Standard-quality 32 768 Hz resonators of this type are warranted to have a long-term accuracy of about six parts per million (0.0006%) at 31 °C (87.8 °F): that is, a typical quartz clock or wristwatch will gain or lose 15 seconds per 30 days (within a normal temperature range of 5 to 35 °C or 41 to 95 °F) or less than a half second clock ...

The clock face with its clock positions is a heritage of Roman civilization, as is suggested by the survival of Roman numerals on old clocks and their cultural predecessors, sundials. The mechanical clock supplanted the sundial as the major timekeeper, while the Hindu–Arabic numeral system replaced the Roman as the number system in Europe in ...
