Docker Timezone in Ubuntu 16.04 Image

containers, datetime, docker

Solution

Updating `/etc/timezone` is the usual way, but there's a bug in Xenial which means that doesn't work.

Instead you need to create a link from the desired timezone to `etc/localtime`:

FROM ubuntu:xenial     
RUN ln -fs /usr/share/zoneinfo/US/Pacific-New /etc/localtime && dpkg-reconfigure -f noninteractive tzdata

Problem

I have created a Docker container using the Ubuntu 16.04 image. ``` docker run -it -d --name containername -v /var/www/public --privileged ubuntu ``` after creating the container, I checked the date inside the container: ``` $ date Tue Oct 25 08:10:34 UTC 2016 ``` But, I need it to use the Asia/Kolkata timezone. So I tried changing the `/etc/timezone` file, then `docker stop` and `docker start` the container, but it doesn't work. It still shows the same time. How can I change the time zone in the Docker container after creating it?
