Yeah, but that's the general datetime input code, which has rather
different goals than to_timestamp().
After thinking about it I'm inclined to feel that SS and friends should
insist on exactly 2 digits. If you want to allow 1-or-2-digits then use
FMSS, just like the error message tells you. (However, I have a vague
feeling that Oracle doesn't insist on this, and in the end we ought to
follow Oracle's behavior. Can anyone check?)
In any case, it's certainly broken that the last field behaves
differently from not-last fields. I'm not all that set on whether we
insist on two digits or not, but I do think the inconsistency needs
to be fixed.
