Dear Tom,<br>
<br>
the semantic property you are interested in may be shared by the
perfective aspect of more languages. Another one is Cabecar
(Chibchan). Similarly as in Russian (salvo errore), the perfective
most of the time refers to past events, but reference to future
events is possible. It seems that such a behavior of an aspect
morpheme is not quite the same as the semantics of temporal adverbs
that have been adduced. These latter do refer to points or periods
of time, whereas the perfective views the event in question in its
entirety, including the boundaries of its extension in time. This is
straightforwardly possible for past events, but requires additional
interpretive effort for future events. What I am saying is that the
perfective aspect may not quite meet the requirement of your initial
quest about "time reference".<br>
