I would like to point out that using July as a time is problematic,
as I believe that:
(cl:comment 'C employs P during time interval T'
(employs C P July)
would say that July is a time interval.
To my way of thinking, July is the name of the (infinite) set
of all time intervals that can be classified as overlapping with
the month of July in any year.
Thus, the statement (employs IBM Fred July)
says that IBM employs Fred during the month of July in
every possible year. (perhaps Fred is a seasonal worker)
This is a different statement by far than saying IBM employs
Fred for a particular month of July in a particular year.
I expect also that the 3-D vs 4-D time view would argue
that it is actually a time-slice of Fred that is employed rather
than the Fred that exists at all times.
