Thanks for the tips from this post:

https://medium.com/better-programming/docker-tips-synchronize-container-timezone-with-host-machine-via-docker-compose-in-ubuntu-18-04-6f01615efc24

Two changes must be added in docker-compose.yml. First need to add TZ in enviroment, then add localtime and timezone in Volumns.

Like so

environment:
– TZ=Europe/Berlin

volumes:

- /etc/localtime:/etc/localtime:ro
- /etc/timezone:/etc/timezone:ro
