don't convert DATE values.
2001-07-10 Damon Chaplin <damon@ximian.com> * src/libical/icaltimezone.c (icaltimezone_convert_time): don't convert DATE values. * src/libical/icaltime.c (icaltime_from_timet_with_zone): (icaltime_as_timet_with_zone): changed so they do not convert DATE values according to the timezone. * src/libical/icaltime.[hc]: added icaltime_current_time_with_zone() and icaltime_today() functions. svn path=/trunk/; revision=10983
