Don't know how to do locale, but javascript is a client side technology.

<pre><code>usersLocalTime = new Date();
</code></pre>

will have the client's time and date in it (as reported by their browser, and by extension the computer they are sitting at). It should be trivial to include the server's time in the response and do some simple math to guess-timate offset.

I mix the answers so far and add to it, because I had to read all of them and investigate additionally for a while to display a date time string from db in a user's local timezone format.

The datetime string comes from a python/django db in the format: 2016-12-05T15:12:24.215Z

Reliable detection of the browser language in JavaScript doesn't seem to work in all browsers (see <a href="https://stackoverflow.com/questions/1043339/javascript-for-detecting-browser-language-preference">JavaScript for detecting browser language preference</a>), so I get the browser language from the server.

Python/Django: send request browser language as context parameter:

<pre><code>language = request.META.get('HTTP_ACCEPT_LANGUAGE')
return render(request, 'cssexy/index.html', { "language": language })
</code></pre>

HTML: write it in a hidden input:

<pre><code>&lt;input type="hidden" id="browserlanguage" value={{ language }}/&gt;
</code></pre>

JavaScript: get value of hidden input e.g. en-GB,en-US;q=0.8,en;q=0.6/ and then take the first language in the list only via replace and regular expression

<pre><code>const browserlanguage = document.getElementById("browserlanguage").value;
var defaultlang = browserlanguage.replace(/(\w{2}\-\w{2}),.*/, "$1");
</code></pre>

JavaScript: convert to datetime and format it:

<pre><code>var options = { hour: "2-digit", minute: "2-digit" };
var dt = (new Date(str)).toLocaleDateString(defaultlang, options);
</code></pre>

See: <a href="https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString" rel="nofollow noreferrer">https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString</a>

The result is (browser language is en-gb): 05/12/2016, 14:58

In JS there are no simple and cross platform ways to format local date time, outside of converting each property as mentioned above. 

Here is a quick hack I use to get the local YYYY-MM-DD. Note that this is a hack, as the final date will not have the correct timezone anymore (so you have to ignore timezone). If I need anything else more, I use moment.js. 

<pre><code>var d = new Date(); 
d = new Date(d.getTime() - d.getTimezoneOffset() * 60000)
var yyyymmdd = t.toISOString().slice(0,0); 
// 2017-05-09T08:24:26.581Z (but this is not UTC)
</code></pre>

The d.getTimezoneOffset() returns the time zone offset in minutes, and the d.getTime() is in ms, hence the x 60,000.

I want the server to always serve dates in UTC in the HTML, and have JavaScript on the client site convert it to the user's local timezone.

Bonus if I can output in the user's locale date format.

Display date/time in user's locale format and time offset

数据库

服务器

Django

Python

我希望服务器始终在超文本标记语言中使用UTC格式的日期，并让客户端站点上的JavaScript将其转换为用户的本地时区。如果我可以以用户的区域设置日期格式输出，则会获得奖励。
