to explain this. There is no notion of "univeral time", whether
'interval' or
not in SR or GR. Proper time is not universal,

Sure proper time is universal....it is invariant and universal time is
invariant.

Invariant in what? If you say precisely what proper time is invariant
under, then then your statement will be either true or false. As it
is, it's just nonsense.

The rate passage of proper time is the same in all frames of reference and
this is what it mean by the state that proper time is invariant. The rate of
passage of clock time (clock seconds) is different in different frame of
reference and this means that clock time is not invariant.



No. The clock second in the observer's frame is "proper time", by no
means
'universal'. How could it be, when even simultaneity is not universal?

This is a bogus assertion. Simultaneity is absolute and universal.

SR, which you've said to be a subset of your own theory, says different:

http://www.bartleby.com/173/9.html

SR is a subset of IRT because IRT includes the following:
1. A moving clock appears to run slow because a clock second on the moving
clock contains a larger amount of proper time.
2. Light path length of a rod is contracted because the rod is in a lower
state of absolute motion than the observer......it takes light to travel a
shorter distance to cover the length of the rod when the rod is in a lower
state of absolute motion.
3. Light path length of a rod is expanded because it has a higher state of
absolute motion than the observer.....it takes light to travel a longer
distance to cover then length of the rod.
