Abstract
This paper presents an interval-based modal logic for specification of real-time systems and knowledge representation. A real-time system is understood as a time-dependent dynamic entity whose attributes can be observed and changed by performing actions. We take linear and dense time as our underlying time model, which can be characterised by the rationals. In our formalism, modal operators on formulas are defined by time intervals and modal operators on terms are defined by time instants and actions. Actions are not instantaneous but take some time to be performed. Different actions can take place at the same time. The proposed logic can also allow to specify obligations and prohibitions of actions over a period of time in deontic sense.
