The logic of event clocks. Decidability, complexity and expressiveness. (English) Zbl 0978.03015
Summary: In this paper we define the real-time logic of event clocks. This logic is inspired by event clock automata. The logic is defined, illustrated and shown to be decidable in PSPACE by a simple decision procedure that relies on a reduction to event clock automata. The expressive power of the logic is compared to known formalisms.
