Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Your format string includes "m" as in month twice. You need an "i" for minutes.

date("Y-m-d h:i:s",$i);
 [2011-02-08 21:03 UTC] greg at pwsdb dot com 
echo  '<br>' . date("h:m:s a");
produces 
02:02:26 pm 
and (4 sec. later) 
my interactive fedora 14 command $ date 
produced 
Tue Feb  8 14:58:30 EST 2011
which is correct: It is 58 minutes after the hour, not 2 right now. 
... therefor, it is the date function in PHP, not linux, and it is not
the strtotime function. this time, it was not involved.
