Sheesh. You cannot read? ("well after it has been calibrated")

The counter counts interrupts as you say ( or seconds ) but unless you
tell it what time it started it cannot do anything but count seconds
since the computer was turned on. IF from outside you tell it that it
started at some number of seconds after Jan 1 1970, then yes, it can add
that to the number of counts to get seconds since epoch.

Precisely.

Since you know epoch you know what the real time is. (and yes, real time
is somewhat arbitrary.24 hours in a day, 60 min/hour, 60 sec per minute
is an "arbitary" but by now universally agreed on division of time.

Well, you may be right, or it may count seconds and convert internall. I
do not know which it does, and suspect different RTCs behave differently
internally.
