Setting the TZ variable will work. There isn't a /etc/timezone, /etc/localtime, or /usr/share/zoneinfo in the container

$ docker run -d --rm --name rabbit -e TZ=CST rabbitmq:3.7.17-alpine

If you have further questions you could also try asking over at the Docker Community Forums, Docker Community Slack, or Stack Overflow. Since these repositories are for issues with the image and not necessarily for questions of usability
