Time in the theory of relativity: inertial time, light clocks, and proper time

Abstract: In a way similar to classical mechanics where we have the concept of inertial time as expressed in the motions of bodies, in the (special) theory of relativity we can regard the inertial time as the only notion of time at play. The inertial time is expressed also in the propagation of light. This gives rise to a notion of clock – the light clock, which we can regard as a notion derived from the inertial time. The light clock can be seen as a solution of the theory, not as an independent concept, which complies with the requirement that a clock to be so must have a rate that is independent from its past history.
