Not exactly. If you have you own the datetime (so refcount=1), and you
call grl_media_set_creation_date(), Grilo will increase the refcount as
a way of saying "I'm an owner too".
So after returning refcount is increased in 1.

You should call it, or you will have leak. The function increases the
refcount to have a reference.
GDateTime *d = g_date_time_new_now_utc();
//d->refcount == 1
grl_media_set_creation_date (media, d);
//d->refcount == 2

Yes.
Following the above example:
GDateTime *new_d = grl_media_get_creation_date (media);
//new_d->refcount == d->refcount == 2
