It looks really good, though I'm not able to try your code out. For some reason EasyPHP don't support public- and private-declarations.

I've some small suggestions to your code. Now when you're working with a class, then why don't you encapsulate $starttime, $endtime, $elapsed and $timername? This would give your code a better design, and the user will not be able to reach the variables directly, they've to use the functions. Beside that, you usually don't initialize the variables where you're doing it. It's done in the constructor (__construct())

Very nice, I've got this working flawlessly

I'm glad you could make use of it. Just out of curiosity - what did you use it for?
