It may be equipped to imprint additional data not related to time. It may be actuated manually or automatically by card insertion. It incorporates provisions for automatic, semiautomatic, or manual precise positioning of lined, and/or columned "in and out" time cards, "elapsed time" job cards, and the like. For similar items not having provisions for precise positioning, see STAMP, TIME. See also CLOCK, RECORDING, WATCHMAN'S. For instruments designed to measure the total operating time of a circuit, machine or system, see METER, TIME TOTALIZING.

A Time Stamp (STAMP,TIME) is a mechanically or electrically operated clock which is primarily designed to imprint time data on letters, documents, and the like. It may be equipped to imprint additional data not related to time. It may be actuated manually or automatically by insertion of the item to be stamped. It does not incorporate provisions for precise positioning of the stamp. For similar items which incorporate provisions for precise positioning of the stamp, use RECORDER, TIME.

A Stopwatch is a timepiece designed exclusively to indicate a time interval, with reference to measurement. It may be started and stopped at any given instant, and controlled by a start and stop mechanism. Excludes Timer as used to control, regulate, or register a fixed time interval which has been previously determined.

What is an Interval Timer?

An Interval Timer (TIMER,INTERVAL) is an instrument for signalling the expiration of a predetermined time. It may also have an automatic switch for control of electrical circuits See also TIMER, STOP.

What is a Master Regulating Clock?

A Master Regulating Clock (CLOCK,MASTER REGULATING) is a precision clock having a mechanism for controlling and regulating secondary clocks. It may not have any device for actuating bells or other signals.

What is a Stop Timer?

A Stop Timer (TIMER,STOP) is a precision instrument for measuring and indicating elapsed time periods. Not intended to be carried on the person. See also TIMER, INTERVAL.

What is a Shelf Clock?

A Shelf Clock (CLOCK,SHELF) is a clock designed to set atop a shelf, mantel, desk, table and the like. It does not have an alarm mechanism, but may have chimes and/or strike mechanism. For clocks with an alarm, see CLOCK (1), ALARM.

What is a Mechanical Marine Clock?

A Mechanical Marine Clock (CLOCK,MARINE,MECHANICAL) is a clock having a spring-wound movement, contained in a moisture-proof plastic or metal case designed for mounting on a vertical surface.

What is a Wall Clock?

A Wall Clock (CLOCK,WALL) is a clock specifically designed for mounting on or in a wall. It may have chimes and/or strike features. It shall not have any mechanism for controlling and regulating secondary clocks or alarm signalling devices.

What is a Time Totalizing Meter?

A Time Totalizing Meter (METER,TIME TOTALIZING) is an instrument that automatically measured, and cumulatively registers the total operating or idle time of any circuit, machine or system, to which it is connected. See METER, FREQUENCY AND TIME TOTALIZING, ELECTRICAL.

What is an Electric Clock Movement?

An Electric Clock Movement (CLOCK MOVEMENT,ELECTRIC) is an item consisting of an electric motor and necessary gear assembly to actuate the dial indicators, or pointers of a clock, in respect to time. Does not include the dial, pointers or indicators.

What is a Chronometer?

A Chronometer is an instrument for precisely determining time, manufactured to close tolerances to assure the time-keeping qualities of dependability and consistency of rate. These qualities are accurately ascertained by comparison with more exact devices or by astronomical methods so that the accumulated error may be taken into account when determining time. Its usual uses are to indicate time for navigational purposes, and to serve as a reference for less accurate timepieces. It is usually provided with a winding indicator dial and is usually mounted in gimbals to maintain the instrument in a level position. May consist of a spring driven or other type of movement which is capable of exacting performance without regulation throughout the normal range of room temperatures. Not designed for carrying on the person.

What is a Panel Clock?

A Panel Clock (CLOCK,PANEL) is a clock specifically designed for mounting on or in a panel. It may have a strike mechanism. Excluded are mechanisms for controlling and regulating secondary clocks and alarm signalling devices.

What is a Watchman's Clock Recording Key?

A Watchman's Clock Recording Key (KEY,RECORDING,WATCHMAN'S CLOCK) is an item that registers embossed impressions on a type fibre/paper time dial. Impressions are made directly from raised numerals or letters on the item or may require the use of ribbons, carbon, or inking devices for legible impressions.

What is a Watchman's Clock Station?

A Watchman's Clock Station (STATION,WATCHMAN'S CLOCK) is a container used to store a key for a CLOCK, RECORDING, WATCHMAN'S. May be lockable and may include the key and/or chain.

What is a Sequential Timer?

A Sequential Timer (TIMER,SEQUENTIAL) is an item which actuates included electrical contacts and/or switches in an orderly succession, and at a predetermined interval(s) for the purpose of controlling the operation of another electrical device(s). May have provision for manually establishing an operational sequence or cycle. See also RELAY, MOTOR DRIVEN; TIMER, INTERVAL; KEYER (as modified); CHRONOMETER, MAKE-BREAK CIRCUIT and INTERVALOMETER (as modified).

What is a Time Code Generator?

A Time Code Generator (GENERATOR,TIME CODE) is a device specifically designed for use as a central timing device for the purpose of providing time-correlated signals for magnetic tape recorders, oscillographs, strip chart recorders, cameras, digital printers, remote digital displays or direct computer entry. The device may generate various time code formats, contain special features for time comparisons against broadcast time signals and provide visual display in BCD or decimal format.

NATO Supply Class 6645 refers to Time Measuring Instruments, which are categorized under NATO Supply Group 66 for Instruments and Laboratory Equipment.

Time Measuring Instruments in this class are used for measuring and indicating time intervals, durations, or specific points in time. These instruments are commonly used in various industries, including scientific research, manufacturing, aviation, and telecommunications.

Some examples of Time Measuring Instruments in this class include:

1. Clocks: These are devices that display the current time and are commonly used for general timekeeping purposes.

2. Timers: These instruments are used to measure and indicate specific time intervals or durations. They are often used in laboratory experiments, cooking, and sports events.

3. Stopwatches: These handheld devices are used to measure and record the time elapsed between the start and stop of an event. They are commonly used in sports, athletics, and scientific experiments.

4. Chronographs: These instruments combine the functions of a watch and a stopwatch. They can measure and record both the current time and elapsed time.

5. Time Recorders: These devices are used to record the time of events or actions, typically in a workplace setting. They are often used for attendance tracking and timekeeping purposes.

It is important to note that NATO Supply Class 6645 includes a wide range of time measuring instruments, each with its own specific features and applications. When selecting a time measuring instrument, it is essential to consider the intended use, accuracy requirements, and any specific features or functionalities needed for the task at hand.
