t1, t2, tB, AB, c, and 0 are numbers. Numbers are the same for
everyone, including A and B, and therefore the realtions between
the numbers are the same, too.

No, the numbers are not the same for everyone.
Let's take the case of the Langevin traveler, Vo=0.8c. D=2*12al.

 Richard, it seems to me that you're conflating two different
situations, which causes monumental confusion.  The case that
was under discussion was synchronizing two clocks at rest with
respect to each other, not the case where the clocks are in
relative motion, n'est-ce pas?

It is even worse than that: he conflates the reading of a *single*
clock at a single event with the readings of two clocks.
He is basically claiming that for some observers 3 can be 4.
He is highly demented.
