Abstract
In many of his writings Russell developed a theory of time, highly interesting both from a philosophical and from a logical point of view. Strangely enough, this has not acquired general attention. The most important relational properties of the duration and points of time will be presented. In addition, Russell's considerations on the existence and density of time points will be critically analysed and systematically reconstructed. A. G. Walker's explication of the concept of time point is unlike that of Russell. His theory of time reflects the Dedekindian concept of cut. Walker's constructions will be modified in a suitable way and supplemented so that it becomes possible to prove the continuity of the temporal series.
