Description:
------------
$_SERVER['REQUEST_TIME'] seems to fluctuate. 4 runs of 

$_SERVER['REQUEST_TIME']: 4.4291801813059E+17
time(): 1290528694

$_SERVER['REQUEST_TIME']: 4.4291801813268E+17
time(): 1290528708

$_SERVER['REQUEST_TIME']: -3.689152654376E+18
time(): 1290528722

$_SERVER['REQUEST_TIME']: 2.2138054492136E+18
time(): 1290528739


Test script:
---------------
<?php
	header('Content-Type: text/plain');
	
	echo "\$_SERVER['REQUEST_TIME']: ", $_SERVER['REQUEST_TIME'], "\ntime(): ", time(), "\n";

Expected result:
----------------
$_SERVER['REQUEST_TIME'] to be approximately inline with time()

Actual result:
--------------
Wonky.
