They do, and adding that check is part of what I pushed yesterday: https://github.com/Gnucash/gnucash/commit/44c278a82c692b5b591eccaf052952b3cd248084
But the rest of that function is a bit goofy and regardless strptime is very fussy: If you tell it to parse the date with %m/%d/%Y and pass in--as Fred did--5.19.21--it will return NULL indicating that the parse failed. We can do much better.
