Bug description: date function slower than in 5.0.5
Description:
------------
Has the date function slowed from PHP 5.0.5 to PHP 5.1.1?
When testing with the code below, my output is:
PHP 5.0.5: 0.044
PHP 5.1.1: 0.938
If I comment out the $d = ... line, my output is:
PHP 5.0.5: 0.003
PHP 5.1.1: 0.001
...so I know it's the date function that is responsible for the slower
time.
Has anyone else seen evidence of this?
(I'm using Windows XP SP2 with the PHP Zip packages)

Reproduce code:
---------------
<?php
function get_microtime() {
list($usec,$sec) = explode(" ",microtime());
return((float)$sec + (float)$usec);
}
$t1 = get_microtime();
for ($x=0; $x<10000; $x++) {
$d = date("Y-m-d H:i:s");
}
$t2 = get_microtime();
printf("%.3f\n",($t2-$t1));
?>
