This paper proposes a set of representations for tenses and a set of constraints on how they can be com- bined in adjunct clauses. The semantics we propose ex- plains the possible meanings of tenses in a variety of sen- tential contexts. It also supports an elegant constraint on tense combination in adjunct clauses. These semantic representations provide insights into the interpretations of tenses, and the constraints provide a source of syntac- tic disambiguation that has not previously been demon- strated. We demonstrate an implemented disambiguator for a certain class of three-clause sentences based on our theory.
