Ensure timezone/time data is synced in docker
Especially in app containers, because this can affect the verification of HTTP signatures and break federation.
One way to do that could be to add the following volumes to our sample docker-compose.yml, for each service:
volumes: - "/etc/timezone:/etc/timezone:ro" - "/etc/localtime:/etc/localtime:ro"
And update our mono-container installation guide to include those volumes as well:
-v /etc/timezone:/etc/timezone:ro -v /etc/localtime:/etc/localtime:ro
