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?

Answer 1

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.

Answer 2

It's the number of milliseconds since 1/1/1970. To convert to human readable, Add that many milliseconds to a 1/1/1970 date object.
