when running
<?PHP
print date("d/m/Y", strtotime("31 July 2001"))."\n";
print date("d/m/Y", strtotime("-1 month", strtotime("31 July 2001")))."\n";
?>

it replies with 
X-Powered-By: PHP/4.0.3pl1
Content-type: text/html

31/07/2001
01/07/2001

of course what it's doing is turning it into 31 june which is then being considered to be the 1 of july.. Should this be right or should strtotime realise that there are 30 days in june and truncate the "31st" day?

Confirmed with php 4.2.0-dev.

print date("d/m/Y", strtotime("1 month ago", strtotime("31 July 2001")))."\n";

Gives the same error, and that should be correct GNU date syntax?

R.

Not really a bug, it's exactly like GNU date behaves:

[derick@kossu derick]$ date --date='31 July 2001 -1 month'
Sun Jul  1 00:00:00 CEST 2001
