We introduce extensions of the UML class, object and statechart diagrams and define the semantics of the UML extensions by means of extended timed graphs (XTG), a timed automata variant. This approach opens the possibility to specify properties of the UML specifications using the timed computation tree logic. The transformation of the UML-specification into XTG allows the verification the system by model checking using the LPMC model checker tool, which uses XTG as its input language.
