如何保证setTimeout准确性

# 系统时间修复法

function timer() {
   var speed = 500,
   counter = 1, 
   start = new Date().getTime();
   
   function instance()
   {
    var ideal = (counter * speed),
    real = (new Date().getTime() - start);
    
    counter++;
 
    var diff = (real - ideal);
    form.diff.value = diff;
 
    window.setTimeout(function() { instance(); }, (speed - diff)); // 通过系统时间进行修复
 
   };
   
   window.setTimeout(function() { instance(); }, speed);
}
