Docker file is missing option to set php timezone

[Germs2004]

Fresh install using this docker command that was recommended in your readme file:
docker run --name phpservermonitor -p 80:80 -d quentinv/phpservermonitor:latest

On the install.php page, it gives a warning:
You should set a timezone in your php.ini file (e.g. 'date.timezone = UTC').

I think the correct solution to this is for your docker image to have an option for the user to specify the timezone while installing the docker image. This issue from a different project may be helpful:
