Change localtime openhab2 docker

Hi

How do i change system local time in openhab2 i am running OH2 in docker on my qnap Ts-451P

You don’t. You change a system’s time in the system.

but my qnap time is GMT+1 but openhab2 is GMT so i dont know how to chance this

I don’t know what that means. As far as I’m aware, OH doesn’t have a time of its own, but gets its time from either the system it’s running on or from another external system.
