            Bug ID: 451459
           Summary: Korganizer displays wrong start/end times for
                    recurrences over DST boundary and created in UTC
           Product: korganizer
           Version: unspecified
          Platform: Gentoo Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: agendaview (weekview)

the KOrganizer window that demonstrates this bug

SUMMARY
If I create a recurring event in UTC and it goes past a DST boundary,
korganizer will use the tz offset at the first instance of that event as the
displayed start/end time for *all* recurrences of that event.

STEPS TO REPRODUCE
1. Switch system timezone to America/Toronto
2. Create an event that starts at 2022-02-26 5:00 PM and ends at 2022-02-26
5:00 PM with *timezone set to UTC*, and repeats every week
3. Take a look at the Feb 26 instance and Mar 19 instance in Agenda/Week view

OBSERVED RESULT
In 3, the block of the Mar 19 instance is aligned with "1pm-2pm," but the start
and end time on the block is "12:00 P.M. - 1:00 P.M." Clicking on the event and
the details docker on the left sidebar says "Time: 12:00 P.M. - 1:00 P.M."

EXPECTED RESULT
In 3, the block of the Mar 19 instance is aligned with "1pm-2pm," the start and
end time on the block should be "1:00 P.M. - 2:00 P.M." Clicking on the event
and the details docker on the left sidebar should say "Time: 1:00 P.M. - 2:00
P.M."
