Description:
------------
http://git.php.net/?p=php-src.git;a=commitdiff;h=f89effd2a83de2b1d6381f9b9403a8328e0998b6
On 6.nov.2010 Ilia Alshanetsky "Updated _SERVER['REQUEST_TIME'] to include microsecond precision". This introduced a breaking change - since then variable returns miliseconds instead of seconds.

http://git.php.net/?p=php-src.git;a=commitdiff;h=86c44e119fd71eeed6f3bc213d544a06cc4a13e5
On 23.jun.2011 someone finally noticed, and he "Fixed a bug with calculation of REQUEST_TIME in apache2". However, he only fixed apache2handler and omitted apache2filter.

The bug breaks existing code that uses $_SERVER['REQUEST_TIME'] in timestamp comparisons and assumes that its value is in seconds. I tested the attached patch and it fixes the issue (hopefully not introducing other issues).
PS: $_SERVER['REQUEST_TIME_FLOAT'] is also affected.

Test script:
---------------
<?php
	$rt = $_SERVER['REQUEST_TIME'];
	$now = time();

	echo $rt."\n";
	echo $now."\n";
	echo ( strlen((string)$rt) == strlen((string)$now) ) ? "OK" : "Error!";
?>


Expected result:
----------------
1341752154
1341752154
OK


Actual result:
--------------
CLI/CGI:
1341752154
1341752154
OK


MOD_PHP5:
1341752154539
1341752154
Error!
