Consider please the Lorentz transformation for the time coordinates of the same event t'(E)=g(t(E)-Vx/cc) (1) where g stands for gamma and t(E) and t'(E) for times displayed by clocks synchronized following Einstein's procedure. My question is: with what times displayed by how synchronized clocks should I replace t(E) and t'(E) in order to arrive at absolute simultaneity. The synchronization procedure should be faisible and in accordance with that proposed by Einstein. I know so far the "everyday" clock synchronization which leads to such result. Thanks in advance.
