Version 1.05 of the code is uploaded. It will remove anything that isn’t a digit from the input. If it can’t guess the “invalid date” message now includes a hint on the format.
Still a limit is that you need the leading zero in things like date or hour and the order must be yyyy/mm/dd hh:mm:ss.
If you want to you can send me pictures of your build and then I will put them up on the gallery
