Abstract
In many of his writings Russell developed a theory of time,highly interesting bothfrom a philosophical and from a logical point of view.Strangely enough, this has not acquired generalattention. The most important relational propertiesof the duration and points of time will be presented.In addition, Russell's considerations on the existenceand density of time points will becritically analysed and systematically reconstructed.A. G. Walker's explication of the concept of timepoint is unlike that of Russell. His theory oftime reflects the Dedekindian concept of cut.Walker's constructions will be modified in a suitableway and supplemented so that it becomes possileto prove the continuity of the temporal series
