Detect the ID of the current user timezone using moment.js

Question

What I\'m looking for is a way to detect the browser\'s timezone ID (as defined in the Olson tables) but I don\'t care for the exact ID, I just need the ID of a timezone tha

Answer 1

I made a small script to do that detection. It starts by registering the ids of the available timezones, then, on a call to the matches function tests all timezone ids for the current time and the times 4 and 8 months later (to filter out the timezones with different daylight rules) and five years before.

Here it is :

If you just want one timezone id, simply use

var tzid = tzdetect.matches()[0];

Update : The code here shown isn't compatible with the most recent versions of moment.js. Please refer to the GitHub repository for a maintained (free to use) code.

2017 Update: There's now an API in moment.js to guess the timezone. That's probably the best solution right now.
