是否可以确定指令的时间跨度？

我有一个问题，我无法通过谷歌搜索，因为我真的不知道它的正确术语（如果概念存在的话）。我的问题是这样的；

想象一下 C 中有一个 while 循环，它执行 1 个内联汇编指令

__asm { mov eax, ebp };

然后我们将分别使用 printf 打印它的输出。但是否有可能确定“时间”何时正好达到 1 秒呢？

我正在对 ASLR 进行一些研究，我想通过查看随机化是否彼此间隔恰好 X 秒来查看每次随机化之间是否有固定的时间跨度。

希望您理解，并感谢您的阅读/帮助。

I have a question, which I was unable to Google because I really don't know the proper terminology for it, if concept exists that is. My question is this;

Imagine having a while loop in C, which does 1 inline assembly instruction

__asm { mov eax, ebp };

Then we would print it's output with printf, respectively. But would it be possible to determine when "time" has reached exactly 1 second?

I'm doing some research on ASLR, and I want to see if there is a fixed timespan between each randomization by seeing if the randomization occures exactly X seconds apart from each other.

Hope you understand, and thanks for reading/helping.
