In all my running docker containers the containers system time is set to UTC whereas on my host (debian) its CEST.

Why dont they sync automaticly? How do i make them set the right time when bringing them up?

You should be able to set timezone in your containers by using tzdata :

docker run -e TZ=Europe/Amsterdam debian:jessie date

    From docker-compose.yml, it's TZ: yourtzname under the environment key.
