Timezone appears not to be working

[Hafnernuss]

In my docker-compose file, I have set up the timezone as "Europe/Vienna":

environment:
      - TZ="Europe/Vienna"

with the folling in my config.yml file:

archive_name_format: 'myservice-files-{now:%Y-%m-%d_%H-%M-%S-%z}'

However, the backups are created in the following format:

myservice-files-2024-08-18T07:46:46+0000

Which appears to be plain UTC. Am I missing something here or is the TZ env not honored?

What does docker exec -it Borgmatic date give you?

I've just checked on mine, and the TZ variable is definitely honoured.

Just a quick one: At my compose.yaml, the environment node is not an array, but a dict. So, maybe instead of your example above, lose the dash at the beginning, and replace the = by ': '. Like so:

environment:
      TZ: "Europe/Vienna"

This is the way it works for me.

This is mine in case it's useful:
