Many safety-critical software applications are hard real-time systems. They have stringent timing requirements that have to be met. We present a description of timing behaviour that includes precise definitions as well as analysis of how functional timing requirements interact with performance timing requirements, and how these concepts can be used by software designers. The definitions and analysis presented explicitly deal with tolerances in all timing durations. Preliminary work indicates
