I have build a JS fiddle for you with best performance and easiest handling:

http://jsfiddle.net/ojzw2hfu/

Put a hidden input into the form, setup an interval function to update the input and on submit stop the timer. The value includes Microseconds but I'll leave it up to you to find a way to cut that out ;-)

var startTime;
var endTime;
var timer;


$(document).ready(function() {
    startTime = performance.now();

    timer = window.setInterval(function() {
        endTime = performance.now();
        $('#timer').text(endTime - startTime);
    });

});

$('#myForm').on('submit', function() {
    window.clearInterval(timer);
    $('#millisecondValueInForm').val(endTime - startTime);
    return false; //remove this later in real script because it prevents form from submitting
});
