I updated the title to reflect the Docker container. Should help get the proper eyes on this topic for you. 🙂

You can either set the `TZ` env variable for your container, e.g. `docker run -e TZ="Europe/London"`, or you can modify ignition.conf and add a line to the additional parameters section that sets `-Duser.timezone=Europe/London`.
