A framework for the specification of parallel and distributed real-time systems is presented by using the formal specification language Z. To this end, a general approach to safety and fairness conditions and timer concepts are developed in Z. As a case study the framework is applied to the well-known Generalized Railroad Crossing Problem, whereof a complete specification and a proof of the required safety and liveness properties are included.
