How do you practically check your "t = t'" equations for clocks standing next to each other?

I read the numbers they display and I compare them.
Good.
Then for distant mutually at rest clocks with no
gravity involved?

I don't.
Sad. You don't. You can't. We can.
No you can't either. Sorry, There is a small technical detail: those
"distant clocks" are not moving wrt each
other.
How do you ensure that? By assuming the
condition a priori;and you can do it because
you're only applying your procedure
in your gedanken. Am I incorrect ?
You are. I put two clocks at the extremity of a rod. This is quite reasonable to assume they are at rest wrt to each other, isn't it? Given that you've once pretended that the cities of Gdansk and Warsaw are in relative motion, I'm not sure I'll get a sensible answer here by the way :-D
You're only believing [into] a great
practical procedure - because your is pumping you with gedanken fairy
tales where it works fine.
Nope. If such a procedure would fail it could be checked. Checking is part of the procedure.
> Putting two clocks aside is not quite a delusion.
It was not about "putting two clocks aside".
it was about putting them aside in some space
lacking any gravity and after ensuring (by some
untold magic) that they're not moving wrt each
other. Practically - both these requirements
are some utter absurd.
No magic, and if gravity could not be ignored in a given practical setup this can be spotted (see below).
As I wrote you can ensure both clock are at rest wrt each other (these days is even doing that with satellites, did you hear about recent ESA experiment on artificial eclipses ?), just use a rod.
Then apply, in *practice* (a word you know NOTHING about):
1. Check synchronicity
2. If not in sync use the measured values at stop 1 to offset one clock or both of them
3. Wait for a while
4. Check again. If the clocks are still in synch then you have shown that previous assumptions and that the procedure is consistent
