When displaying a date in a listbox, always configure a specific
listbox_date editable Date-Time field in the form.
This allows that the date is displayed in the listbox according to
the user date format preference. In ERP5, the most used searchable dates are
delivery.start_date and delivery.stop_date. Using these dates in a listbox
allows to do some filtering by dates. The column must be named "delivery.start_date",
and the editable field must have id "delivery_start_date"
