Abstract: Due to the absence of abilities to describe temporal factors entirely in Object-Z,such as describing the execution of operations at some specific time or in some cycles,and the absence of concept of operation compensation,the paper presented DTL-Real-Time Object-Z:an integration of real-time Object-Z with the Distributed Temporal Logic.The language can express the event-driven,time-driven and compensation factors of operations effectively.The syntax and semantics of the language were analyzed and discussed.Finally,expressiveness and application of the language were showed by formal description of an obligation authorization model.

Key words: Formal description language,Obligation authorization model,Object-Z,Distributed temporal logic
