Updating <code>/etc/timezone</code> is the usual way, but there's a <a href="https://bugs.launchpad.net/ubuntu/+source/tzdata/+bug/1554806" rel="noreferrer">bug in Xenial</a> which means that doesn't work.

Instead you need to create a link from the desired timezone to <code>etc/localtime</code>:

<pre><code>FROM ubuntu:xenial 
RUN ln -fs /usr/share/zoneinfo/US/Pacific-New /etc/localtime &amp;&amp; dpkg-reconfigure -f noninteractive tzdata
</code></pre>

You have to do <code>rm /etc/localtime</code> because of the <a href="https://bugs.launchpad.net/ubuntu/+source/tzdata/+bug/1554806" rel="noreferrer">Ubuntu bug</a>.

blocks|key|630798|text|作为在这里说，秘诀是dpkg-reconfigure+tzdata只创建/etc/localtime作为拷贝、硬链接或符号链接(符号链接是首选的)，而不是/usr/share/zoneinfo中的文件。因此，完全可以通过您的Dockerfile来完成这一任务。考虑：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|630799|ENV+TZ=America/Los_Angeles
RUN+ln+-snf+/usr/share/zoneinfo/$TZ+/etc/localtime+&&+echo+$TZ+>+/etc/timezone|code-block|syntax|javascript|630800|作为奖励，TZ也将正确地设置在容器中。|630801|这也是与发行版本无关的，所以它几乎适用于任何Linux。|630802|entityMap|0|LINK|mutability|MUTABLE|url|https://serverfault.com/a/683651/93281^0|A|N|10|E|25|J|2|4|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@$9|X|A|Y|B|C]|$9|Z|A|10|B|C]|$9|11|A|12|B|C]]|D|@$9|13|A|14|1|15]]|E|$]]|$1|F|3|G|5|H|7|16|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|17|8|@]|D|@]|E|$]]|$1|M|3|N|5|6|7|18|8|@]|D|@]|E|$]]|$1|O|3|-4|5|6|7|19|8|@]|D|@]|E|$]]]|P|$Q|$5|R|S|T|E|$U|V]]]]

As <a href="https://serverfault.com/a/683651/93281">said here</a>, the secret is that <code>dpkg-reconfigure tzdata</code> simply creates <code>/etc/localtime</code> as a copy, hardlink or symlink (a symlink is preferred) to a file in <code>/usr/share/zoneinfo</code>. So it is possible to do this entirely from your Dockerfile. Consider:

<pre><code>ENV TZ=America/Los_Angeles
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime &amp;&amp; echo $TZ &gt; /etc/timezone
</code></pre>

And as a bonus, TZ will be set correctly in the container as well.

This is also distribution-agnostic, so it works with pretty much anything Linux.

My issue has been solved with this very simple solution (<a href="https://serverfault.com/a/826222">https://serverfault.com/a/826222</a>) : Add timezone in environment variable.

The command is <code>docker run -e TZ=Europe/Amsterdam ...</code>

Or, using docker-compose, like I do : 

<pre><code>version: '3'
services:
 web:
 build: ./app
 ports:
 - ...
 volumes:
 - ...
 environment:
 - TZ=Europe/Paris
</code></pre>

In my case, no more tzdata needed, or volume share with /etc/timezone &amp; /etc/localtime. 
Hope it helps !

<li>-3 corresponds to Moscow time. For Berlin set -1 . If you need positive value, set UTC2</li>

I have created a Docker container using the Ubuntu 16.04 image. 

<pre><code>docker run -it -d --name containername -v /var/www/public --privileged ubuntu
</code></pre>

after creating the container, I checked the date inside the container:

<pre><code>$ date
Tue Oct 25 08:10:34 UTC 2016
</code></pre>

But, I need it to use the Asia/Kolkata timezone. So I tried changing the <code>/etc/timezone</code> file, then <code>docker stop</code> and <code>docker start</code> 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?
