我怎么知道现有计时器的准确度? [英] How can I know the exact accuracy of an existing timer?

问题描述

我不需要HPET计时器，但是我不擅长编程，对基本设备的了解甚至更少.

I am in need of a HPET timer while I am not good at programming and know even less about the basic device.

所以我提出了一个问题.这似乎很愚蠢，但我只是不清楚:

So I have kept a question.It seems to be really sily,but I just can't make it clear:

当我有一个现有的计时器时，这应该是我可以达到的最高精度.如果找不到更精确的参考，如何测量其精度?

When I have an existing timer,which is supposed to be almost the highest accuracy I can make to.How can I measure the accuracy of that if I haven't found a more precise reference?

我的英语不好，所以我希望自己不要感到困惑.

My English is poor,so I wish I hadn't make it confusing.

中文描述说它可以达到1ms的精度.如何确保我们能真正达到这个精度?如果我想提高它，如何检查校正后的精度?

the Chinese description says it can reach an accuracy of 1ms.How to make sure we can really get this precision?If I want to improve it,how to check the corrected one's precision?
