Abstract dialectical frameworks (ADFs) are one of the most powerful generalization of classical Dung-style AFs. In this paper we show how to use ADFs if we want to deal with acceptance conditions changing over time. We therefore introduce so-called timed abstract dialectical frameworks (tADFs) which are essentially ADFs equipped with time states. Beside a precise formal definition of tADFs and an illustrating example we prove that KleeneÂŘs three-valued logic K3 facilitate the evaluation of acceptance functions if we do not allow multiple occurrences of atoms.
