Indeed, I understand the "varying times" situation. While I'm fairly familiar with perlmod. I appreciate your pointing those sections out.

Reason for asking; is that I had an inclination to add a timer to a page template I had just created, and wanted to see how it performed, compared to the one I had been using. It occurred to me, given that there are so many different Time related Modules available. Is/would there be a better one than the one(s) I had chosen. If so. How would I know (without a great deal of bench testing). It all seemed so impractical. Then, as I thought how one should be implemented. I figured, surely I'm not the only one that has had to deal with this. So I searched PerlMonks. Then based on the results. Decided to see if I could discover, or reach some consensus on this.

I think, given the input you, and others have provided:

• It simply isn't possible to obtain a more accurate results, without a few millisecond deviation.
• Consensus can only be obtained via averaging; and even then results will differ from OS to OS.
