Just a challenge. I didn't like that you couldn't get this result simply using the TIMESTAMP_FORMAT scalar alone, so I wanted to see what it would take to clean up the resulting data so that the converted number could be recognized and worked with. Using the scalar alone made the result field difficult to test against (see Rob's second post to this thread).

I wrote it for fun. I excluded RPG because I wanted to exercise my SQL skills.

The OP needed to ID dates in numeric fields, this does that.

Our shop won't allow downloaded, free code without significant vetting. One way around this is to write it myself.

Now that I've got this written, I thought to wrap the logic into a UDF because our shop has these 8-digit numbers that represent dates in every table. Converting these to timestamps makes date arithmetic much easier, whether the language is RPG or SQL.

Any particular reason why?

I am completely with you if you just want to challenge yourself.
Exercise your brain and all that. But then you say this:

Probably not as clean as idate (didn't look at it), but it does the
job. I think that I'll wrap this in a UDF.

So, you need this for your live system. For work. Presumably at an actual business.

Tell me again why RPG was not an option?
