Subject: Re: [PHP-DEV] Overriding Default Functions
From: pollita@php.net ("Sara Golemon")

Specifically, you want to enable the (under-documented)
runkit.internal_override INI option.  It's mentioned on the reference page,
but with no explanation of what it does.  I need to make a language-snippet
for that at some point....

This was added in version 0.6 (prior versions could only override
user-defined functions/methods).  If you enable this option (PHP_INI_SYSTEM
only) you can use runkit_function_redefine() to replace the builtin time()
with something else.

I think runkit is what you're looking for.
