Is a proper second represent a specific interval of absolute time???

Definition for a proper second: it is a second at the rest frame of a

clock.

The answer to this question is yes.

Why?

Because a clock second in the rest frame of the clock does represent a

specific interval of absolute time. However, it is important to

realize that a clock second does not represent the same interval of

absolute time in different frames....this is the reason why clocks in

different frames run at different rates. This means that one can't

compare clock second accumulated during the journey of a clock to a

clock second accumulated on the stay at home clock. This means that

the twin paradox never happen in terms of absolute time.

The math of SR/GR is design to determine the clock time value on an

observed clock for an interval of proper time (absolute time) on the

observer's clock. The GPS supports this interpretation. The GPS

second is redefined to have 4.46 more periods of Cs 133 radiation.

This redefinition of the GPS second is designed to make the GPS second

contains the same amount of absolute time as a ground clock second and

thus making the GPS in synch with the ground clock permanently.

A new theory of relativity called IRT uses this interpretation. IRT

includes SRT as a subset. However, unlike SRT, the equations of IRT

are valid in all environments, including gravity. A paper on IRT is

available in the following link:
