Increasing complexity in distributed and real-time systems makes them very hard to model and specify correctly. Different formal methods are useful for the process of modeling and specification of these kinds of systems. Timed  Automata  (TA)  and  Distributed  Timed  Automata  (DTA)  are  the  dominant  models  of  distributed  and  real-time  systems.  Unfortunately,  their  language  inclusion  and  complementation  are  undecidable.    In  this  paper,  we  will  present  logics  and  automata  (Distributed  Event  Clock  Automata  (DECA),  Memory  Event  Clock  Automata  (RMECA), Distributed Event Clock Temporal Logic (DECTL), Memory Event Clock Temporal Logic (RMECTL) fully decidable and they were designed to modeling, specifying and studying the behavior and in particular verifying the correct operation of distributed and real-time systems.
