It is impossible to synchronize two watches A and B located in different places.
It is not a technical problem, it is not a problem of intelligence, it is simply that it is as impossible as finding a round square, or a natural number between 5 and 6.
Because nature is not made like that.
Anyone who wants to synchronize watches with each other does not realize that he is looking for rabbit horns.

The only thing we can do is to find a kind of abstract, imaginary synchronization procedure, called the Einstein procedure where tAB is supposed to be equal to tBA not only for the point M which is the only real origin of the synchronization, but for everyone.

So the only thing we can do is to do what Einstein did,
namely to define a synchronisation procedure which
makes it possible to synchronise two clocks at different
places in an inertial frame of reference.

 That's for sure the only thing [you]
can do. Professionals of GPS could do more.
 

Sure ! Thanks to GR. As Paul wrote in another post :

Note that clocks showing UTC are synchronous in the non-rotating
Earth centred frame of reference (ECI-frame), but they are NOT
synchronous in the ground frame.
Note the rather peculiar phenomenon that the UTC clocks
are synchronous in the frame were they are moving, but
not synchronous in the frame where they are stationary.

BTW. You are posting here because you love to be spanked, aren't you?
