我为您提供了最佳性能和最简单处理的JS小提琴：

http://jsfiddle.net/ojzw2hfu/

将隐藏的输入放入表单中，设置间隔函数以更新输入并在提交时停止计时器。该值包括微秒，但我会留给您找到一种方法来减少它; - ）

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
});
