If you expected a paper on synchonization at LHC to be written by Albert

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.

Nice signature though.
