On one side, computer science concentrates on temporal reasoning in controlled industrial environments, typically using discrete events and time intervals, neglecting spatiotemporal dependencies (e.g. Theodoulidis and Loucopoulos 1991, Ligozat and Vila 1998, Cowley and Plexousakis 2000). Allen’s logic, for instance, is only temporal - not spatiotemporal. (In fact it is included in the CRM). Allen (A llen 1983) searches/refers to techniques (by describing relationships between temporal intervals) available for representing time knowledge in general applications as needed in Artificial Intelligence
