Wrong Time in Rules

I am running OH 4.3.5 on a raspberry pi 5. My rules use the wrong time zone. I already found the problem. The Time zone in /etc/default/openhab is set to Europe/London instead of Europe/Zurich.

When I connect to the Raspberry pi using WinSCP I receive a ‘permission denied’ error.

What do I need to do to change this file?

Open a console connection to the Pi and then sudo nano /etc/default/openhab (or whatever is the actual config file name).

Thank you very much.
