No, but you can use microtime() to generate a timer at the start and at
the end of your page, and minus them.

Apart from microtime(), if your PHP version is great or equal than 5.1.0
you should have a variable called $_SERVER['REQUEST_TIME'] that contains
a Unix timestamp of when the request was received. That allows you to
count time until the first line of the script is actually executed.
