Peter it is a great idea - almost a design flaw of the timediff function.
If you are unfamiliar with the RFE system then I can post it for you - just
give me a shout . However I think you should give the RFE a try.

Is it possible to do that without having an IBM customer ID?

Subject: TIMESTAMPDIFF() result should be BIGINT instead of INTEGER
Hi Everyone,
On a v7r3 box, I was using timestampdiff to determine the duration of
a job in microseconds. I'd never used it before, but it seemed pretty
straightforward, but the result was ++++++++++++++
SELECT JOB_NAME
, JOB_ACTIVE_TIME
, JOB_END_TIME
, TIMESTAMPDIFF(1, char(JOB_END_TIME - JOB_ACTIVE_TIME)) uSeconds
FROM TABLE(QSYS2/JOB_INFO( JOB_USER_FILTER => 'myusrid')) JI
WHERE JOB_NAME = '123456/myusrid/myjob'
JOB_NAME JOB_ACTIVE_TIME JOB_END_TIME USECONDS
123456/myusrid/myjob 2021-05-08-06.20.48
2021-05-08-07.46.29 ++++++++++++++
The problem is that for some reason, TIMESTAMPDIFF() returns INTEGER.
microseconds is about 35 minutes and 47 seconds. Any job whose duration is
longer gets SQLSTATE 22001 or diagnostic message CPD5036 "Data mapping
error on member QSQPTABL." reason 27, which is "27 -- For the CAST
operation, the character destination field is too short to hold all the
significant digits of the source."
And when there is no explicit CAST operation in the SQL statement, andseveral possible implicit CAST operations, time is wasted figuring out
where the problem actually is.
It seems like BIGINT would have been a better choice. 8 bytes gives 2^63or 9,223,372,036,854,775,808 microseconds (signed), or over 106,751,991
days. The consumer of the result can choose to put their result into a
smaller variable.
These days, microseconds is overkill, so I dropped back to just secondsto resolve my problem, but it still seems like a poor choice of result size
for TIMESTAMPDIFF.
