ADATIM in classes and representations

SUGGESTED

Hi there,

I'm trying to use the datatype ADATIM in classes and representations to manipulate departing times and estimated delivery times.

The problem is every time I try to edit the field I get the error "invalid format type"

Here is a print screen of this problem:

It's impossible to use the format: "YYYY[-]MM[-]DD[T]hhmmss[Z]" because max length is 12 chars.

What should I do? Best Regards
