Check out
<http://publib.boulder.ibm.com:80/cgi-bin/bookmgr/BOOKS/QB3AGZ03/4.4.93>
which describes how to use the SUBDUR opcode in RPG IV to determine the
difference between two times.

Refer to
<http://publib.boulder.ibm.com:80/cgi-bin/bookmgr/BOOKS/QB3AGZ03/2.3.5#HDRDTIME>
for a general discussion on using the time datatype in RPGIV.

(Yeah, I know, you probably want an answer relating to RPG III.
But learning RPG IV is really a "no-brainer" and doing the time
computations in RPG IV are a heck of a lot easier than figuring
out some complex formulas.)
