I think there may have been a misunderstanding.  I was already using
attrgetter, my problem is that it doesn't appear to be sorting by the
argument i give it.  How does sort work with strings?  How about with
datetime.time or datetime.date?

So far i can get it sorting strictly by the datetime objects, but i
need all of this sorting done within the constraints imposed by doing
sorts via department and engagements.

Any ideas?
