Maciej,
You have now switched from discussing clocks to discussing
synchronization.
These are not the same thing.
Of course synchronization is not a local operation.
Nobody has ever claimed otherwise.
Synchronization is a procedure relating two or more distant clocks.
An individual clock, however, is a local physical device.
It measures the elapsed time along its own worldline.
Those are two completely different concepts.
Einstein never wrote that clocks are "local" in the sense that they
cannot be synchronized.
Quite the opposite.
His 1905 paper begins by introducing local clocks and immediately asks
how distant local clocks can be synchronized.
That question occupies an entire section of the paper.
So your conclusion
"According to Einstein ... it shouldn't happen."
is exactly backwards.
Synchronization is not forbidden.
It is defined.
In fact, without a synchronization convention, there is no operational
meaning to statements such as
"these two distant events happened at the same time."
Your own GPS example depends on this.
GPS works because each satellite carries a local atomic clock, and the
system continuously synchronizes those local clocks to a common time
scale.
The existence of a synchronization procedure does not make the clocks
non-local.
It merely establishes a relation between several local clocks.
