Proper time is the pseudo-Riemannian arc length of world lines in four-dimensional spacetime. From the mathematical point of view, coordinate time is assumed to be predefined and an expression for proper time as a function of coordinate time is required.

Proper time is also called clock time, or process time, and it is a measure of the amount of physical process that a system undergoes. For example, proper time for an ordinary mechanical clock is recorded by the number of rotations of the hands of the clock.
If you’ve had special relativity, you recognize this as the square of the proper time difference Δτ between the two spacetime events. (The proper time — often called wristwatch time in EBH — is the physical time in an inertial reference frame in which both events are simultaneous.) Sometimes
Hace 6 días · Overview. proper time. Quick Reference. The time as measured by any observer from a clock at their location that is stationary with respect to them. In the theory of relativity, time is said to be proper to each observer.
Definition: Proper Time. The proper time is an invariant quantity that can be determined from the spacetime interval. Another name I like to use for proper time is wristwatch time*, because it is the time interval measured by an inertial observer who is present at both events.
