I have a question similar to that presented in this post.

I need to be able to find out how long it took to do something, but very precisely. So simply getting time(); before and after I call my subroutine won't work--I need accuracy down to, say, milliseconds.

I think this could be done with Time::HiRes, but I too am in a situation where I can't use modules. Can anyone help?
