It seems like there is a bug where if you pass a
fromtime toschedule.next_occurrencesthat is close to the DST boundary, you can get future occurrences that occur on the wrong time.E.g. A recurring appointment that occurs every Sunday at 01:15 am London time. If you call
schedule.next_occurrences(from_time)where from_time is just prior to March 27, 2022 01:00 am, all occurrences shift an hour forward to 2:15 am local time.
