Caldav is splitting full day events on two days

Configuration
1

Hello everyone, I have integrated my Nextcloud calendar into HA. The normal events are displayed correctly, all full day events are displayed twice.

The events were created either with an iPhone or via Thunderbird. The time there is always from 00:00 to 00:00.

But Home Assistant now splits this event to 23:00 to 00:00 before the actual appointment and 00:00 to 23:00 on the correct events day. So I always have two entries in my calendar. One event before and one event on the right day.

Is this a known bug? Is there a possibility to do something about it?

calendar:
  - platform: caldav
    username: home-assistant
    password: !secret caldav
    url: https://cloud.example.de/remote.php/dav

Does not appear to be a known issue:

Ok. It looks like a user interface bug. It is correct in the app and also in Chromium. In Firefox the calendar is displayed incorrectly.

To me it looks like some time zone setup issue between server and client (one hour shift). Or perhaps between device you create the event and one you see it via HA. Can you verify consistency of these between different setup components?
