Right, time is an emergent aspect, dependent on the continuity of a chronology.
Yes, and you can only assign a specific time to the actual expressed duration (short or long) of the chronology. Those periods of duration are called individual time-lines for each chronology, regardless of length. There are bundled time-lines for sets of related simultaneous chronologies. But when an event stops for any reason it's associated time-line disappears and there is no time at all, except for the individual or bundled time-lines of other chronologies.
And of course the universe (space) has its own timeline. That is what we refer to as the fourth dimension of space and created the term spacetime. It is true that all individual time-lines occur within the universal spacetime, but that only depends on the continued existense of the spacetime geometry. There is no time outside of spacetime. There is nothing outside of the universe, except a timeless abstract "permission" (the act of
permitting)...
