So you need to remove specific text, do you?

That might sound yoda-esque. Oh well.

< ?php
$checknow ==time();

if (date($checknow) < 13) {
    echo 'This is before 3pm:
       '. date('Y-m-d') ."\n";
    }
elseif (date($checknow) > 13) {
     echo 'This is after 3pm: 
       '. date('Y-m-d') ."\n";}
?>

Not pretty, but functional.
