In what date format is 1339698600000 = 15 June 2012?

datepicker, datetime, twitter-bootstrap

Solution

That is the number of milliseconds since January 1, 1970 (POSIX epoch). You can divide it by 1000 to get the number of seconds since epoch which is a standard way to represent time.

Problem

I am using bootstrap-datepicker and get a value of 1339698600000 for the selected date of 15th June 2012. What dateformat is this? How do I convert it to human readable format? Is there any resource where I can find many more formats?
