Okay, I've reviewed the online man page for date and time functions, and I've played with
several likely candidates, and I am still having trouble subtracting two arbitrary
Datetimes to get something that is useful. A simple subtraction yields the least useful
thing possible: a modulo-100 difference of modulo-60 quantities. Other functions yield
the proper answer, but not for a quantity of time that rolls over midnight, etc.

You mean timestamps that are less than a full day apart?
"TIMESTAMPDIFF(SECOND, ...)" does not work for you? There is also "TO_SECONDS".
