We consider the problem of model-checking a parametric extension of the logic TCTL over timed automata and establish its decidability. Given a timed automaton, we show that the set of durations of runs starting from a region and ending in another region is definable in the arithmetic of Presburger (when the time domain is discrete) or in the theory of the reals (when the time domain is dense). With this logical definition, we show that the parametric model-checking problem for the logic TCTL can easily be solved. More generally, we are able to effectively characterize the values of the parameters that satisfy the parametric TCTL formula.
