Abstract

According to Dennis Dieks, in the theory of relativity, the «flow of time» results from the succession of events along time-like worldlines. We have a flow of time per worldline. This leads to a view of now as local to each worldline. In this approach there is no global temporal order of the now-points of different worldlines. For a consistency reason it is imposed a limitation on the assignment of different now-points. Here it is made the claim that this consistency requirement is inbuilt in the theory, and it is presented a detailed analysis of this approach.
