Thank you very much for the digging! That is the solution for having the 
datetimes parsed correctly when entered in the right format in the frontend!

But still - what can I do, if a frontend user by mistakes does not enter the 
date in the right format 'd.m.Y'? In 
extbase/Classes/Property/TypeConverter/DateTimeConverter.php on line 125 
there is an Exception being thrown in that case, which results in a TYPO3 
error page for the user. I don't see a way yet to prevent this from 
happening. Maybe I'm still not getting the overall concept, but I the 
desired behaviour should probably be to get a form error  in the frontend 
(it was like that with the old property manager)and not a fatal error like 
that.

Any ideas?
