  This paper presents an analysis of temporal anaphora in sentences which
contain quantification over events, within the framework of Discourse
Representation Theory. The analysis in (Partee 1984) of quantified sentences,
introduced by a temporal connective, gives the wrong truth-conditions when the
temporal connective in the subordinate clause is "before" or "after". This
problem has been previously analyzed in (de Swart 1991) as an instance of the
proportion problem, and given a solution from a Generalized Quantifier
approach. By using a careful distinction between the different notions of
reference time, based on (Kamp and Reyle 1993), we propose a solution to this
problem, within the framework of DRT. We show some applications of this
solution to additional temporal anaphora phenomena in quantified sentences.
