According to <a href="http://groups.google.com/group/nodejs/browse_thread/thread/b35802578e0a62b4?pli=1" rel="noreferrer">this google group thread</a>, you can set the TZ environment variable before calling any date functions. Just tested it and it works.

<pre><code>&gt; process.env.TZ = 'Europe/Amsterdam' 
'Europe/Amsterdam'
&gt; d = new Date()
Sat, 24 Mar 2012 05:50:39 GMT
&gt; d.toLocaleTimeString()
'06:50:39'
&gt; ""+d
'Sat Mar 24 2012 06:50:39 GMT+0100 (CET)'
</code></pre>

You can't change the timezone later though, since by then Node has already read the environment variable.

blocks|key|734446|text|另一种方法似乎至少在Linux环境下对我有效，那就是像这样运行你的Node.js应用程序：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|734447|env+TZ='Europe/Amsterdam'+node+server.js|code-block|syntax|javascript|734448|这至少应该确保从一开始就正确设置了时区。|734449|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Another approach which seemed to work for me at least in Linux environment is to run your Node.js application like this:

<pre><code>env TZ='Europe/Amsterdam' node server.js
</code></pre>

This should at least ensure that the timezone is correctly set already from the beginning.

Unfortunately, <a href="http://github.com/joyent/node/issues/3286" rel="noreferrer">setting <code>process.env.TZ</code> doesn't work really well</a> - basically it's indeterminate when the change will be effective).

So setting the system's timezone before starting node is your only proper option.

However, if you can't do that, it should be possible to use <a href="https://github.com/TooTallNate/node-time" rel="noreferrer">node-time</a> as a workaround: get your times in local or UTC time, and convert them to the desired timezone. See <a href="https://stackoverflow.com/a/10825774/1005455">How to use timezone offset in Nodejs?</a> for details.

blocks|key|734982|text|只需在主文件中设置环境变量，如index.js、app.js、main.js或其他文件名：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|734983|process.env.TZ+=+"Asia/Tehran";|code-block|syntax|javascript|734984|这将设置将在整个节点应用程序中使用的时区|734985|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

just set environment variable in your main file like index.js or app.js or main.js or whatever your file name is:
<pre><code>process.env.TZ = &quot;Asia/Tehran&quot;;
</code></pre>
this will set the timezone which will be used in your entire node application

Set server timezone and use NTP sync.
Here is one better solution to change server time.

To list timezones

<pre><code>timedatectl list-timezones
</code></pre>

To set timezone

<pre><code>sudo timedatectl set-timezone America/New_York
</code></pre>

Verify time zone

<pre><code>timedatectl
</code></pre>

I prefer using UTC timezone for my servers and databases. Any conversions must be handled on client. 
We can make used of moment.js on client side. 

It will be easy to maintain many instances as well,

You could enforce the Node.js process timezone by setting the environment variable <code>TZ</code> to <code>UTC</code>

So all time will be measured in UTC+00:00

Sometimes you may be running code on a virtual server elsewhere - That can get muddy when running NODEJS or other flavors.

Here is a fix that will allow you to use any timezone easily.

<a href="https://en.wikipedia.org/wiki/List_of_tz_database_time_zones" rel="nofollow noreferrer">Check here for list of timezones</a>

Just put your time zone phrase within the brackets of your FORMAT line.

In this case - I am converting EPOCH to Eastern.

<pre><code>//RE: https://www.npmjs.com/package/date-and-time
const date = require('date-and-time');

let unixEpochTime = (seconds * 1000);
const dd=new Date(unixEpochTime);
let myFormattedDateTime = date.format(dd, 'YYYY/MM/DD HH:mm:ss A [America/New_York]Z');
let myFormattedDateTime24 = date.format(dd, 'YYYY/MM/DD HH:mm:ss [America/New_York]Z');
