Since this is fixed length and the only variable is the value of the

opposed to substringing the timestamp elements and testing those values.

Personally, I try to avoid using regex if it's at all practical.
What's practical depends on a few factors, of course.

In your particular case, I think I would write an RPG program which
takes a string as input and returns whether the input was of the
required form. Within that RPG program, I would use BIFs and no regex.
