    Abstract:

    This paper discusses the semantics on temporal variable “Now”, that is, “Now” may express the meaning about “current”, “past” and “future” time in a valid time, and based upon this semantic analysis, the paper studies the corresponding issues for determining the temporal value of “Now” and gives a formal algebra system on the calculus of temporal relations.
