Sometimes simple problems don't require the latest and greatest
whiz-bang new fangled language.  This problem doesn't seem very
complex to me:

start.time.in.seconds = seconds + (minutes * 60) + (hours * 3600)

end.time.in.seconds = seconds + (minutes * 60) + (hours * 3600)

Once you have the times expressed in seconds, the math is
pretty simple.  Answer expressed in seconds.

No C required.  No Java required.  No AD/Cycle required.
No SAA required. No Personal Computer involved.  SEU can
be used to enter the source code.  No system API required.
