Look at this repository <a href="https://bitbucket.org/pellepim/jstimezonedetect" rel="noreferrer">pageloom</a> it is helpful

download jstz.min.js and add a function to your html page 

<pre><code>&lt;script language="javascript"&gt;
 function getTimezoneName() {
 timezone = jstz.determine()
 return timezone.name();
 }
&lt;/script&gt;
</code></pre>

and call this function from your display tag

blocks|key|603890|text|不是的。没有唯一可靠的方法，也永远不会有。你真的认为你可以相信客户吗？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|603891|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

No. There is no single reliable way and there will never be. Did you really think you could trust the client?

blocks|key|603953|text|就目前而言，最好的选择可能是mbayloon's+answer中建议的jstz。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|603954|为了完整性，应该提到的是，在它的道路上有一个标准：Intl。你可以在Chrome中看到这一点：|603955|>+Intl.DateTimeFormat().resolvedOptions().timeZone
"America/Los_Angeles"|code-block|syntax|javascript|603956|(这实际上并不遵循标准，这是坚持使用该库的另一个原因)|603957|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/6939685/get-client-time-zone-from-browser/8984850#8984850|1|http://norbertlindenberg.com/ecmascript/intl.html^0|E|H|0|0|P|4|1|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@$A|X|B|Y|1|Z]]|C|$]]|$1|D|3|E|5|6|7|10|8|@]|9|@$A|11|B|12|1|13]]|C|$]]|$1|F|3|G|5|H|7|14|8|@]|9|@]|C|$I|J]]|$1|K|3|L|5|6|7|15|8|@]|9|@]|C|$]]|$1|M|3|-4|5|6|7|16|8|@]|9|@]|C|$]]]|N|$O|$5|P|Q|R|C|$S|T]]|U|$5|P|Q|R|C|$S|V]]]]

For now, the best bet is probably jstz as suggested in <a href="https://stackoverflow.com/questions/6939685/get-client-time-zone-from-browser/8984850#8984850">mbayloon's answer</a>.

For completeness, it should be mentioned that there is a standard on it's way: <a href="http://norbertlindenberg.com/ecmascript/intl.html" rel="noreferrer">Intl</a>. You can see this in Chrome already:

<pre><code>&gt; Intl.DateTimeFormat().resolvedOptions().timeZone
"America/Los_Angeles"
</code></pre>

(This doesn't actually follow the standard, which is one more reason to stick with the library)

blocks|key|819186|text|这是一个jsfiddle|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|819187|它提供当前用户时区的缩写。|819188|以下是代码示例|819189|var+tz+=+jstz.determine();
console.log(tz.name());
console.log(moment.tz.zone(tz.name()).abbr(new+Date().getTime()));|code-block|syntax|javascript|819190|entityMap|0|LINK|mutability|MUTABLE|url|http://jsfiddle.net/b8k1pnzw/^0|4|8|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@$A|V|B|W|1|X]]|C|$]]|$1|D|3|E|5|6|7|Y|8|@]|9|@]|C|$]]|$1|F|3|G|5|6|7|Z|8|@]|9|@]|C|$]]|$1|H|3|I|5|J|7|10|8|@]|9|@]|C|$K|L]]|$1|M|3|-4|5|6|7|11|8|@]|9|@]|C|$]]]|N|$O|$5|P|Q|R|C|$S|T]]]]

Here is a <a href="http://jsfiddle.net/b8k1pnzw/" rel="nofollow noreferrer">jsfiddle</a> 

It provides the abbreviation of the current user timezone. 

Here is the code sample 

<pre><code>var tz = jstz.determine();
console.log(tz.name());
console.log(moment.tz.zone(tz.name()).abbr(new Date().getTime()));
</code></pre>

Half a decade later we have a built-in way for it! 
For modern browsers I would use:

<div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>const tz = Intl.DateTimeFormat().resolvedOptions().timeZone;
console.log(tz);</code></pre>
</div>
</div>


This returns a IANA timezone string, but not <a href="https://stackoverflow.com/questions/1091372/getting-the-clients-timezone-offset-in-javascript">the offset</a>.

blocks|key|819319|text|您可以使用moment-timezone来猜测时区：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|819320|>+moment.tz.guess()

Is there a reliable way to get a timezone from client browser? I saw the following links but I want a more robust solution.

有没有从客户端浏览器获取时区的可靠方法？我看到了以下链接，但我想要一个更健壮的解决方案。
