Abstract The capability to represent and use concepts like time and events in computer
science are essential to solve a wide class of problems characterized by the notion of change. Real-
time, databases and multimedia are just a few of several areas which needs good tools to deal
with time. Another area where this concepts are essential is artificial intelligence because an agent
must be able to reason about a dynamic environment.
In this work a formalism is proposed which allows the representation and use of several features
that had been recognized as useful in the attempts to solve such class of problems. A general
framework based in a many-sorted logic is proposed centering our attention in issues such as the
representation of time, actions, properties, events and causality. The proposal is compared with
related work from the temporal logic and artificial intelligence areas. This work complements and
enhances previously related efforts on formalizing temporal concepts with the same purpose.
Keywords Knowledge Representation, Temporal Logic, Time, Events, Actions, Causality
