Okay, then all is fine - it's expected to be a bit slower. But please,
do not use a setting like US/Eastern, use America/New_York or similar.

I added E_STRICT to the error reporting and saw the messages about the
time zone, so I added "date.timezone = US/Eastern" to my PHP.ini and
now my execution time is 0.125. Adding
'date_default_timezone_set("US/Eastern");' to my script brings it down
to 0.095. Still slower, but much better.

I just checked this on PHP 4.4.1 and the execution time was similar to
that of 5.0.5

Do you have error reporting set to E_ALL | E_STRICT?

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));
?>
