Adding a mere 60 seconds to 2008-12-31 23:59:00 should give a date in 2008, not in 2009. The interval from 2008-12-31 23:59:59 to 2009-01-01 00:00:01 is three seconds. But if the program has kept formatted time stamps from TIME macro, will the difference between CONVTOD of those two values yield the correct result in 64-bit TOD format? IBM shirks providing the necessary documentation. This should not be left to programmers' intuition.
