The Operational Definition of Time

Time = I. The Temporal Principle: A chosen duration (modeled after a natural recurring motion/cycle or an arbitrary duration) called a time-interval can be used for the unit of temporal measurement of the durations between multiple events, the durations of single events, the durations (ages) of people and objects, of space, and of matter-energy (m/e), for the timerate (rate of ticking), timepoints (marks on a timeline, or a continuum of time), timeline (history, record of timepoints on a continuum of time), and timecounts (accumulations by addition for timepoints from the past through the present into the future—the arrow of time being from the past through the present into the future) in timepieces (clocks, watches, etc.), and for the determination of the sequences of events, the simultaneities of events, the causalities of events, and the changerates (rates of change) of events, and for the coordination (synchronization) of events inre single and multiple reference frames/bodies; II. The Temporal Process: The incorporation of chosen time-intervals into the design, fabrication and deployment of timepieces and the use of timepieces' timerates, timepoints, timelines, and timecounts for the temporal measurement of durations and the determination of event sequences, simultaneities, causalities, and changerates, and the event coordination inre single and multiple reference frames/bodies.

The essence of time is the time-interval (TI).

There are two types of TIs: (1) The Variable Time-Interval (VTI) vs (2) The Invariable Time-Interval (ITI).

NOTE: The VTI is also the Local Time-Interval (LTI); The ITI is also the Absolute Time-Interval (ATI).

There are two types of timepieces: (1) The Variable Time-Interval Clock (VTIC) vs (2) The Invariable Time-Interval Clock (ITIC).

There are two types of ITIC designs: (1) The Radio Clock ITIC Design (Master Clock -> Slave Clocks) vs. (2) The Inertial Clock ITIC Design (Accelerometers Linked to Computers).

Radio clocks are found used as standard clocks by the USNO (US Naval Observatory), the US NIST (US National Institute of Standards and Technology), and the BIPM (Bureau Internationale des Poids et Mésures) and the clocks of the US GPS nav system (master clock -> slave clock design, wherein the GPS master clock is synched to the USNO standard clocks and sends radio signals to GPS satellite clocks to regular those clocks' timerates and timecounts—necessary for the successful operation of the GPS nav system).

Inertial clocks are found in the inertial navigation system (INS) aboard US military aircraft, ships, submarines, tanks, etc.

NOTE: VTICs are distortable clocks (non-adjustable clocks); ITICs are adjustable clocks (non-distortable clocks).

NOTE: VTICs are also Local Time Clocks (LTCs); ITICs are also Absolute Time Clocks (ATCs).

There are two types of time: (I) Variable Time-Interval Clock Time (VTICT) vs. (2) Invariable Time-Interval Time (ITICT).

NOTE: VTICT is also Local Time (LT); ITICT is also Absolute Time (AT)

NOTE: VTICT is also distortable time (non-adjustable time); ITICT is also adjustable time (non-distortable time).
