Abstract
We define a causal semantics for Timed Default Concurrent Constraint Programming which permits associating each output with its cause. We show by an example how this information can simplify program debugging. We prove that the classic operational semantics of the language can be recovered from our causal semantics, and we prove that our causal semantics and the causal semantics of Concurrent Constraint Programming coincide for programs belonging to both languages.
