Docker-machine time zone setting problem

  docker, question

My image:
docker run -it –rm my-boot2docker-img bash
root@f593a2dfb0d8:/# cat /etc/timezone
Asia/Shanghai

Convert to iso file:
docker run –rm my-boot2docker-img > boot2docker.iso

docker-machine create -d xhyve –xhyve-boot2docker-url /MyApp/docker-machine/boot2docker.iso worker1

docker-machine ssh worker1
cat /etc/timezone
UTC

How can we ensure that the time zone is Asia/Shanghai?

Dockfile

RUN echo "Asia/Shanghai" > /etc/timezone

How about this?
