Bug description: strtotime returns -1 randomly
Description:
------------
I read data from mssql server and get dates as "Feb 02 2004 12:00AM". I
read several dates in a loop, and for some dates strtotime returns -1
occasionally, seemingly at random. When I refresh, the wrong result
changes to another date.
$d1 = strtotime($v["date"]);
printf("%s %s<br>", $v["date"], $d1);

This happened when I tested code in Fedora Linux 1, Apache 1.3.29 PHP
4.3.4.
Production version works ok on W2K Apache PHP 4.3.3.
On W2K date strings don't have leading zeros, eg
"Feb 2 2004 12:00AM"
