From 'The Meaning of Relativity', Albert Einstein, 1956:
page 1.
"The experiences of an individual appear to us arranged in a series of events; in this series the single events which we remember appear to be ordered according to the criteria of "earlier" and "later", which cannot be analyzed further. There exists, therefore, for the individual, an I-time, or subjective time."
page 31.
"The non-divisibility of the four-dimensional continuum of events does not at all, however, involve the equivalence of the space coordinates with the time coordinate."
page 32.
"Finally, with Minkowski, we introduce in place of the real time co-ordinate l=ct, the imaginary time co-ordinate..."
A few quotes showing the view of the author of SR.
Note it was Minkowski who advocated the mathematical manipulation of the expression for the invariant interval from an equality to a generalized form of four variables, producing space-time.
It seems there's nothing to separate.
This can be accepted as the 'concluding remarks'; with this, the topic has reached its generally-agreeable 'conclusion'.

I agree!... but have my $.02 to add anyway.
You said, and I agree:

Einstein talked about 'stretching' of 'time'; 'time-dilation'. He should have used a term 'duration', and then told that 'duration' of a process, say decay of a particle, gets stretched. Isn't it?
Yes. Clocks “tick” more slowly the faster they go... or the deeper into a ‘gravity well’.
Making “time” into ?something? that “dilates” or “stretches” is one of the two primary misconceptions behind relativity theory, along with also reifying space and then "weaving" both misconceptions together into the “fabric of spacetime”... which then gets “curved by mass” as an explanation of how gravity works. ...
...Being as fields of gravitational force generated by masses and extending beyond them was arbitrarily discarded in favor of the fantasy fabric.
No question that the math&model, the new tool of GR was an improvement over Newtonian gravity... but Newton couldn’t handle the “action at a distance” part of gravity... as an attracting field of force between masses... so Einstein and Minkowski invented “spacetime.”
Yet science refuses to even ask the (merely ontological) question, "What is it exactly that mass is supposed to curve?" Empty space (where not occupied by "stuff", obviously) and the concept of "duration" or "elapsed time" as things move?
I agree that Phyti has summed it up very clearly.

Folks,
To me, time is a property of discrete matter and it passes at rates inversely proportional to an object's speed in space. It accrues to discrete objects only and is not imposed as a so-called "fabric of space" over the universe.
