Description Joerg Schiermeier 2022-01-20 18:55:33 UTC
First:
I use the file "std.ics" from "$HOME/.local/share/korganzier" to control my public calendar on my website.

Than:
Last week I discover that this stopped working because the stored "DTSTART" and "DTEND" have different data formats. This changed when I updated the plasma/KDE last week. Before it was working flawlessly for a lot of years.

Look at this, please:

DTEND;TZID=Europe/Berlin:20220131T180000

END:VEVENT
---///---

"DTEND" has the timezone included, "DTSTART" does not.
This difference is new. I guess it's a regression.

I haven't been able to reproduce this with the newest versions of KOrganizer and Frameworks.

How did you create the event?  If you used the usual "New Event dialog", were either of the start date and end date set in the "floating" time zone?

Suppose I want to create an event at the 25th of January, 2022, 1:30 P.M. (In Germany this is 13.30 o'clock)
The view is set to the weekly calendar view. Then I will click right on the 25th close to 13.00 o'clock and will choose "Create a new event". I will fill the dialogue. When ready I will hit "OK". Now is done.

> were either of the start date and end date set in the "floating" time zone?
I will not touch the "time zone" buttons.

Enter a new event with KOrganizer.
Comment 5 Joerg Schiermeier 2022-04-16 20:10:08 UTC
This bug still exists in:

KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.90.0
Comment 6 gjditchfield 2022-04-17 03:25:26 UTC
If you click "Zeitzonen >>", what time zones does it reveal?
I suspect that the Start is "floating" (I don't know the translation)
and Ende is "Europe/Berlin".  If that is so, the upcoming release
of KOrganizer 22.04 should fix the problem.

For the sake of completeness, what time zone is selected in
System Settings, Regional Settings > Date & Time?

No. Both are "Europe/Berlin".

There is an untranslated item called "floating". But this item wasn't selected.

Europe/Berlin
Comment 8 gjditchfield 2022-04-21 03:10:50 UTC
I don't know much about Devuan, but I tried to reproduce this in a Docker
container based on Debian Bookworm.  It contains 
KDE Frameworks Version: 5.90.0
Qt Version: 5.15.2
KOrganizer Version 5.19.3 (21.12.3)

Does that match your system?

I created an event, and its dates were recorded correctly:
both DTSTART and DTEND were given TZID=Europe/Berlin.

I do not have any good ideas.  All I can suggest now is that
you add a new ICS file as a calendar, create an event in it,
and see if it is recorded correctly.

I'm sorry to ask this, but didn't you read my description in 
https://bugs.kde.org/show_bug.cgi?id=448846#c0?

Let me answer, what I wrote there:
> KDE Plasma Version: 5.23.5
> KDE Frameworks Version: 5.88.0
> Qt Version: 5.15.2

and

> korganizer Version: 5.18.1

OK. I will do it as you described above. When I shall have some results, they will be published here.

I apologize. Comment #5 mentioned KDE Frameworks Version: 5.90.0;
I thought you had upgraded.

> > korganizer Version: 5.18.1

Thank you.  The KOrganizer version is key information.
