我不需要微米或纳米精度，1毫秒的精度就足够了。
有没有一种合理可靠的方法可以做到这一点？它不是一个关键的应用程序，由于最终的CPU频率缩放或类似的事情而产生的零星错误是可以接受的。我只是想知道这是否可能。我做了一些搜索，除了轮询Chrome的本地计时器构造函数外，找不到超过毫秒精度的计数器。
我还需要以“跨平台和跨浏览器”的方式实现它，因此任何解决方案都需要在大多数配置上实现。
谢谢
/edit:状态更新：我可以排除Javascript、Silverlight和Flash。。但是Java小程序呢？用一个可以达到.1毫秒的精度吗？
在这个问题上付出了更多的努力之后，我得出结论：Java小程序（其中System.nanoTime（）可用，这给了我足够的精度）是目前最好的选择。
兼容性并不理想（至少与javascript一样），但大多数配置已经支持它们，并且每个常见的配置至少都可以支持它们，只需简单下载即可。
不，您将无法在浏览器之间以一致的方式获得接近毫秒的精度。
John Resig写了一篇关于该主题的良好总结。它写于2008年，但总体结论应该仍然有效。
