In this definition of frame, the agreed 'mechanism' you were talking about for zeroing their watches, is actually the Einstein synchronization procedure in the rest frame of that infinite family of observers ?Ibix said:A frame is an infinite family of observers, one at every place in space, all following parallel worldlines, all carrying a three number spatial coordinate, and all agreeing a mechanism for when they should zero their watches. Then the proper time since zero of one of this family is this frame's coordinate time at their location.
Are other mechanisms possibile in principle to do that ?
