Permenent timezone setting

I got a warning that my background processes did not have a start or end time configured and it could impact users. So I created a start of 2am and end of 6am in my config.php.

Because of the time of my systems logs being the wrong timszone i realise i needed to update this so i did.

The only issue is, every time docker restarts, I’m going to lose my timezone settings. Is there a permanent way i can set my timezone?
