TOPIC: Pre-filled date fields

Sorry I got in trouble by generating a hotel registration site with dtregister.
The problem is, for a date field "arrival date" connected with community builder (both set to dd.mm.yyyy) that the date is set to 01.01.1970. Nothing changes by set a pre-filled date at the cb field management to something. Every time it will be the 01.01.1970.
If I change the Profile Sync in DTregsiter of this "arrival date" field not connected to the cb field there is no date pre-filled, it is empty.
Some ideas to solv this problem? I would like to have a arrival date sugesstion as well as departure date suggestion.

Best regards,

Stephan
