Real-time safety-critical systems have both functional and timing requirements. Producing the correct result at the right time is the goal of such systems. The creation of a precise specification of a real-time system is essential for the development of the system. This paper presents a framework that extends the formal specification language Object-Z to incorporate the notion of timing behaviour for specifying real-time systems.
