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

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.

Yeah, sure - "distant" clocks  at the
extremity of the rod - very practical
indeed, isn't it?

  This is quite
reasonable to assume they are at rest wrt to each other, isn't it?

No. Take 2 bodies - one orbitting the other.
Join them with a rod, do you secure their relative
immobility ? Yeah, you imagined and insisted
Gdańsk and Warsaw aren't moving wrt each other. You're
such an idiot.

What is the relative speed between Gdansk and Warsaw then?

Would have to calculate.

LOL!!!

OK, if you ask.
 From wiki - Gdańsk is 54°20′51″N 18°38′43″E,
Warsaw is 52°13′56″N 21°00′30″E.
Assuming the average Earth radius  6368km, Gdańsk
is 3713.3km distant from Earth axis, Warsaw is
3901.5km. That gives 972.1km/h and 1021.4km/h
of linear speed. The difference is 49.3km/h.
Good enough for you as the first estimation,
poor stinker?
Sure, the velocities are not quite parallel;
the final result will be slightly bigger.

You're only believing [into] a great

No magic, and if gravity could not be ignored in a given practical setup

No answer? Of course,

The source?
 http://ttc.web.cern.ch/LEB00Sync.pdf
 But the document is signed "Varela, J", not
"Einstein, A".
If you expected a paper on synchonization at LHC to be written by Albert Einstein you do have more issues than I thought...

And it's definitely
far, far, far more elaborate than the "masterpiece"
of [A. E.]
The practical implementation of a theoretical procedure is more complex than it? Big surprise!
Nevertheless it applied the consequences of tB - tA = t'A - tB and t'A - tA = 2(AB)/V and a signal travelling at speed V.
If you were an engineer you could check that it is equivalent to Poincaré's procedure while far more practical.

Poor stinker. Idiot.
Nice signature though.
