Timezone detection for JavaScript
This library allows you to detect a user's timezone from within their browser. It is often useful to use JSTZ in combination with a timezone parsing library such as Moment Timezone.
This library is an unofficial fork of pellepim/jstimezonedetect. The original library works well and can be used via CDN, but it was not configured to work with NPM. This meant the library was less accessible because it could not be retrieved with a simple npm command or included as a dependency in package.json. Thus this fork was born.
Sidenote: If you're wondering why this isn't an actual GitHub fork it's because the original project uses Mercurial and is hosted on BitBucket.
Dealing with timezones can be a pain. Libraries like Moment Timezone help a lot with the parsing side of things, but if you want to detect the users timezone you would normally have to do it manually. That's where this library comes in.
import jstz from 'jstz';
const timezone = jstz.determine();
timezone.name(); // => 'America/Los_Angeles' (or whatever your user's timezone is)Or if you prefer ES5:
var jstz = require('jstz');
var timezone = jstz.determine();
timezone.name(); // => 'America/Los_Angeles' (or whatever your user's timezone is)Note: If you're not using a module system such as Webpack or Browserify then I recommend you use the original library delivered via CDNJS:
<!doctype html>
<script src='https://cdnjs.com/libraries/jstimezonedetect'></script>
<script>
var jstz = require('jstz');
var timezone = jstz.determine();
console.log('Your timezone is: ' + timezone.name());
