>> I have been looking into temporal database systems. <<




Look up the ressearch done by Rick Snodgrass at the University of
Arizona, and get a copy of his book on temporal databases from
Morgan-Kaufmann.  He is the expert in this area.



The fundamental problems deal with the fact tht time is a continuum
and SQL is based on discrete elements.  You need a very previse model
of time to compare and deal with durations.
