I have a table that contains two datetime columns, and I need to determine
the time between the two dates. So, what I've been doing is just
subtracting what I know is the later date from the earlier date. But that's
obviously not the way to do it as my results don't relate to anything.

You could use the UNIX_TIMESTAMP() function to easily determine
the difference in seconds between the two dates.
select UNIX_TIMESTAMP( Datetime_A ) ...
and the do the time_a - time_b thing. there might be a simple query that
will work as well, but I don't know the mysql date queries that good
