I have just migrated from PHP 4.0.6 to PHP 4.1.0 and I have remarked that the strtotime() is now giving me false results. Look at the following code:

$date_string = "Sat, 15 Dec 2001 01:24:42 +0100 (CET)";
$date_ts = strtotime($date_string);
echo $date_ts;

With PHP 4.0.6 I get the following output (which is correct):

1008375882

And with the new PHP 4.1.0 I get the following output:

1008019482

Which is approxmiately 4-5 days wrong. 

If you need more info feel free to contact me... Thanks for fixing this.

Regards
