I have a JS script for you with maximum performance and simple controls:
Put the hidden input on the form, set up the interval function to update the input and feed the timer stop. The value includes Microseconds , but I'll leave that to you to find a way to cut this; -)
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
});
