Description MAG4 2022-01-18 11:24:46 UTC
SUMMARY
timezone information being lost when copying events (solved by commit 9f4628aa when creating events)
https://invent.kde.org/frameworks/kcalendarcore/-/commit/9f4628aa2c6c90c94fd36d2d4ac8e940adc93680

STEPS TO REPRODUCE
1. Open Korganizer
2. Copy an event with timezone information
3. Export as iCalendar

OBSERVED RESULT
The copied event in the exported .ics file has missing timezone information

EXPECTED RESULT
The copied event in the exported .ics file has timezone information

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Debian Testing
(available in About System)
KDE Plasma Version: 5.23.5
KDE Frameworks Version: 5.90.0
Qt Version: 5.15.0-2

ADDITIONAL INFORMATION
Comment 1 MAG4 2022-02-02 12:32:22 UTC
Thanks to https://bugs.kde.org/show_bug.cgi?id=448846 we investigate further and we find that also moving events directly on calendar views makes timezone information being lost.
Timezone information are correctly saved only if you use Event dialog as https://bugs.kde.org/attachment.cgi?id=145781 (useful as a temporary workaround).
Greetings!

Preserve timezone of original incidence when copy-pasting

The destination date-time provided by the caller will likely be in
local time, but could theoretically be in any arbitrary timezone.
Since we are creating a *copy* it makes sense to preserve the timezone
of the original dtStart/dtEnd/dtDue in the incidence.

Git commit def2b7f4cc507bcf8f64540e77dd736ebb751e7d by Daniel Vrátil.

Agenda: fix timezone being lost when moving event by drag

The code was using QDateTime::toTimeSpec() in attempt to restore the
timezone from the original dtStart/dtEnd. However, QDateTime::toTimeSpec()
automatically converts Qt::TimeZone timespec to Qt::LocalTime, so the
information about timezone was lost and the time was treated as local.

The solution is to restore the timezone manually when the original
timespec was Qt::TimeZone.
