Your implementation context is CGI script, but that is not your application. Your application may be timing a database query or some such. So, what is the application?

You need to decide what it is that you want to report - wall clock time or process time.

With most operating systems that are not designed for real time environments reporting wall clock times of less than a few milliseconds is fairly meaningless because time slices for tasks are of that order and will render any real time reporting at that level meaningless.

Perl reduces RSI - it saves typing
