Thanks for you help!

I was able to do this :

                public void to_time (out Time tm);
                
                public Time toTime () {
                    Time time;
                    to_time ( out time );
                    return time;
                }
                
                public Date.now () {
                    clear();
                    Time timeNow = Time.gm( time_t() );
                    set_year( (GLib.DateYear)(timeNow.year + 1900) );
                    set_month( (GLib.DateMonth)(timeNow.month + 1) );
                    set_day( (GLib.DateDay)(timeNow.day) + 1);
                }
                
                public string to_string () {
                    Time time;
                    to_time ( out time);
                    return time.to_string();
                }

But when doing the same trick to GLib.Time i got

                public Time.gm.now () {
                    Time.gm(time_t());
                }

                public Time.local.now () {
                    Time.local(time_t());
                }

glib-2.0.vapi:1857.3-1857.20: error: missing return type in method
`Time.gm´
                public Time.gm.now () {
                ^^^^^^^^^^^^^^^^^^
glib-2.0.vapi:1861.3-1861.23: error: missing return type in method
`Time.local´
                public Time.local.now () {


I don't know exactly how the VAPI code fits , how to use a contstructor,
do I have access to "this" ...
 
Many thanks!
