Dang it. Hoped it was something simple as changing/updating Java.
But I notice this SystemV/EST5 - that’s a very strange timezone, and since this issue has been about dates, then I’m thinking it could be the cause.
Well, if it works on your Docker, then that’s great - and let’s just leave it at that 
To use your MySQL, you simply just add the environment variables to the Docker run-command, so it uses MySQL for you metadata. Example:
docker run -d -p 3000:3000 -e "MB_DB_TYPE=mysql" -e 'MB_DB_CONNECTION_URI="mysql://<hostname>:<port>/<database>?user=<username>&password=<password>"' --name metabase metabase/metabase
