Hi Carlo,
I believe this is caused by the fact that the minimum DateTime value that can be stored is Friday 1901-12-13 (according to https://docs.mendix.com/refguide/datetime-handling-faq and https://en.wikipedia.org/wiki/Unix_time). I do not believe this can be changed at the moment and would probably require storing the date time values separately (year, month, date, etc. in separate attributes) or as a text.
Hope this helps.
Best regards,
Bart
