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
Modern automated time and attendance systems require employees to touch or swipe to identify themselves and record their working hours as they enter or leave the work area. Originally this consisted of using a RFID electronic tag , a barcode or a QR Code badge but these have been replaced by biometrics (vein reader, hand geometry , fingerprint ...

The most commonly used form was the mechanical clock systems that required a key for manual punching of a number to a strip of paper inside with the time pre-printed on it.
Screenshot of PTPd 2.3.1, an implementation of PTP for Unix-like systems. Precision Time Protocol (PTP) is a widely adopted protocol for delivery of precise time over a computer network. A complete PTP system includes PTP functionality in network equipment and hosts. PTP may be implemented in hardware, software or a combination of both.
Optical cesium atomic clocks - Oscilloquartz has developed optical cesium atomic clocks that are more stable and accurate than magnetic cesium-based solutions and exceed the current ITU-T G.811.1 enhanced primary reference clock (ePRC) specification. The current highest-end clocks in this range combine with core grandmaster devices to provide ...
Included system-oriented layers and troubleshooting, assembly and disassembly aspects. The Advanced Interactive Electronic Technical Manual (A-IETM 1992) was an R&D Augmented Reality (AR) version of this system designed to help to guide the standards used in the mark-up of the documentation - the idea being a UI-independent data stream.

A clock network or clock system is a set of synchronized clocks designed to always show exactly the same time by communicating with each other. Clock networks usually consist of a central master clock kept in sync with an official time source, and one or more slave clocks which receive and display the time from the master.
