How do you set your watch? If observers A and B are not in relative motion, there is no problem. But if A and B are moving relative to each other, they must communicate by light signals. The paper shows how the universal time postulate on the velocity of light, first suggested by Moon and Spencer in 1956, was derived by considering the process of synchronization of clocks. In this paper, the motion of A and B is confirmed to a straight line. The 3-dimensional generalization was obtained by Moon, Spencer and Moon in 1989.
