Calendar on dashboard showing tomorrow's event as today's events

Hi, In my Upcoming events on dashboard, the events that are planned tomorrow are shown as today’s events. When clicking on event, the calendar shows the event on the next day.

NC 20
php7.4
nginx 1.18

This is only a problem with firefox.
I suspect it has to do with the setting of privacy.resistFingerprinting.
But when showing browser date time in http://browserspy.dk/date.php the correct date is given (so not That of tomorrow).

Any ideas what might cause this?

Hi, I would report the bug and include a log to the nextcloud github server repo.
