Abstract: Much recent research has focused on .the need for, and definitions of, historical (or temporal) database and information systems to serve expanding information needs in a variety of applications. Almost all of this research has assumed that the domain of time itself was well-understood, and some representation for it simply needed to be included in the model to provide the needed temporal dimension. In this paper we present a simple, set-theoretic structure for a time domain which is independent of any particular calendric system. We concentrate on the general structure and operations necessary to support the needs arising in modelling time in information systems.
