2000-12-11 Damon Chaplin <damon@helixcode.com> * cal-util/cal-recur.c (generate_instances_for_chunk): updated the tests on the start & end time just before calling the callback. It was skipping occurrences that started before the required interval's start time, which was wrong. We want all occurrences that intersect the interval. (cal_obj_time_weekday): removed the CalRecurrence* argument, since it isn't needed. svn path=/trunk/; revision=6925
