 Docker also solves problems regarding the explicit IPv4 and IPv6 usage (it just supports both). The following
 command will download, "install" and start _py-kms_ and also keep it alive after any service disruption.
 ```bash
-docker run -d --name py-kms --restart always -p 1688:1688 pykmsorg/py-kms
+docker run -d --name py-kms --restart always -p 1688:1688 -v /etc/localtime:/etc/localtime:ro pykmsorg/py-kms
 ```
 If you just want to use the image and don't want to build them yourself, you can always use the official image at the [Docker Hub](https://hub.docker.com/r/pykmsorg/py-kms) (`pykmsorg/py-kms`). To ensure that you are using always the
 latest version you should check something like [watchtower](https://github.com/containrrr/watchtower) out !
