<![CDATA[MM clock reverted to UTC]]>Hi

After a recent reboot (to update MMM-CalendarExt3Agenda and add some more dates to MMM-MyGarbage) I’ve noticed that the clock and agenda modules have reverted to UTC (should be BST right now).

A quick look shows the docker container is now running with UTC (although the RPi is correctly on BST):

magicm@magicmirror:~ $ date
Sun  3 May 09:02:24 BST 2026
magicm@magicmirror:~ $ docker exec -it mm bash
node@magicmirror:/opt/magic_mirror$ date
Sun May  3 08:02:36 AM UTC 2026

I’ve not set the timezone (or date format) explicitly for the Docker before. Has a new release of Docker changed that and, if so, how do I pass that setting through?

Many thanks

Steve

Thanks for the feedback. This is expected behavior. If you really need the timezone for other stuff in the container you can set it by adding this in the compose.yaml:

    environment:
      - TZ=Europe/Berlin

- /etc/timezone:/etc/timezone:ro this should take the timezone from the host.

but the clock and agenda are still on UTC. The Docker logs state this early on
[INFO] ***WARNING*** could not set timezone, please set TZ variable in compose.yaml, see https://khassel.gitlab.io/magicmirror/configuration/#timezone

UPDATE

Before I could send this another day passed and now they are correct! Docker is still on UTC but the Clock and Agenda are correctly showing times on BST!

The external url for getting the TZ doesn’t work anymore, I had to switch to another one. Meanwhile this did not work but I pushed new images some minutes ago which should fix this. So please pull the new image and let me know if it works.
