The following returns time in microseconds, for example 4565212462.
alert( $.now() );
How do I convert it to a human readable time format,
jQuery.now() Returns: Number
Description: Return a number representing the current time.
This method does not accept any arguments.
The $.now() method is a shorthand for the number returned by the expression (new Date).getTime().

It's simple to use Javascript:
var d = new Date();
var time = d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds();
console.log(time);
