In replacement of the ISO format, to avoid any misinterpretation of strings containing accidentally a date, from now on, dates are exchanged between Basic and Python as com.sun.star.util.DateTime structures. The year boundaries are [1900 - 9999]. The code managing the Python-Basic protocol has been changed on both sides. The Basic service receives the - CDateFromUnoDateTime() - CDateToUnoDateTime() methods, equivalent with their Basic homonyms.
