We remark that languages recognized by timed automata in the general case do not satisfy classical Pumping Lemma (PL) well known in the theory of finite automata. In this paper we prove two weaker versions of Pumping Lemma for timed words : a general one (DPL) where iterations preserve the duration of timed word, and another more restricted one, (LPL) when iterations preserve the length of timed word.
