I have seen a related question here, but the answer didn't cover how to sort them by upload date.
Is there any extension/website capable of doing this?

This site offers shuffle and reverse: Youtube Videolist
Videos are sorted by date decremeting by default.
I think there is a good reason why it was not covered, because the sort-by-date filter is right there -
Visit the user's channel(My Channel), click on "Videos" and you can see the filter on right hand side.
