The following returns time in microseconds, for example 4565212462.
alert( $.now() );
How do I convert it to a human readable time format,
The native JavaScript implementation is Date.now().
Date.now() and $.now() return the same value:
Date.now(); // 1421715573651
$.now(); // 1421715573651
new Date(Date.now()) // Mon Jan 19 2015 20:02:55 GMT-0500 (Eastern Standard Time)
new Date($.now()); // Mon Jan 19 2015 20:02:55 GMT-0500 (Eastern Standard Time)
..and if you want the time formatted in hh-mm-ss:
var now = new Date(Date.now());
var formatted = now.getHours() + ":" + now.getMinutes() + ":" + now.getSeconds();
// 20:10:58
