Convert Unix timestamp to ISO 8601

Question

I want to use the jquery timeago plugin - http://timeago.yarp.com/

I have timestamps like this 1331209044000 and the docs say i need an ISO 8601 timesta

Answer 1

Assuming your timestamp is in milliseconds (or you can convert to milliseconds easily) then you can use the Date constructor and the date.toISOString() method.

var s = new Date(1331209044000).toISOString();
s; // => "2012-03-08T12:17:24.000Z"

If you target older browsers which do not support EMCAScript 5th Edition then you can use the strategies listed in this question: How do I output an ISO 8601 formatted string in JavaScript?
