wp-settings.php timezone

I just installed 3.1 and have timezone problems.

I have always had to edit the wp-settings.php file to manually set for my proper timezone but this time it did not work. It does not matter what I have set in the General settings. It seems to look to UTC time regardless of anything I set.

Any ideas? The edit I have had to do in the past is below.

date_default_timezone_set(‘UTC’);

to

date_default_timezone_set(‘America/Phoenix’);
