Calendar shows wrong time

DirkS

Hi, i’m quite out of idea why my calendar shows the appointments with the wrong time. Every time ist 2 hrs to late, ex: an appointment is 8:00 the magic mirror shows 10:00

{
                        module: 'calendar',
                        header: 'Kalender',
                        position: 'top_left',
                        config: {
                        maximumEntries: '25',
                        maximumNumberOfDays: '35',
                        displayRepeatingCountTitle: 'true',
                        colored: 'true',
                        coloredSymbolOnly: 'true',
                        calendars: [
                                        {

I’m running the MM v2.4.1 with a docker container on a debian stretch server. I show a lot of calendars from nextcloud via ics export and from office365, too. But regardless of the source the time is 2 hrs wrong.

Hope somebody can give me a hint.

regards
Dirk
