I personally think, that time is local and 'absolute time' wouldn't make 
sense.

What we call 'time' cannot be universal for several reasons.

One reason: absolute time would require an 'external clock' and a 
mechanism, by which local clocks are synchronized with it.

Iow:

you would need some type of space outside the universe, where the big 
clock ticks and an external watchmaker, who winds it up.

Well, that's hard tobelieve, but eventually thinkable.

The bigger issue is the question, how the 'external clock' could control 
myriads of local clocks.

Another reason:

'absolute time' would be 'one dimensional' and runs only in one 
direction, which is the same everywhere.

That would cause numerous problem, like e.g.

wouldn't it violate energy conservation, if the entire universe pops out 
of a single point?

Or:

how would you balance angular momentum?

(In a big bang universe nothing could spin, if there is no counterpart 
spinning in the other direction)

How about particles?

If there are 'lefthanded' particles, then somewhere need to be 
righthanded particles in equal quantities.


...

Better is actually 'local time'.

Then the local axis of time defines a subset of spacetime, which is 
called 'universe' from that local perspective, while the rest is invisible.

Going to another location which a different local time would show a 
different universe, filled with different stars.
