undefined variable

[mybox]

ragazzi ho questo problema :

Notice: Undefined variable: timeadjust in /home/web/www.sito.net/www/c/web/upload.php on line 152

nella linea 152 ho: (che inizia da $reg)

// now, we start the upload 'process'. That is, to copy the uploaded file
        // from its temporary location to the wanted location
        // It could be something like $handle->Process('/home/www/my_uploads/');
        $handle->Process('usergallery/');
        
        // we check if everything went OK
        if ($handle->processed) {
            // everything was fine !

            echo '  file uploaded with success
';
            echo '  [img]usergallery/' . $handle->file_dst_name . '[/img]
';
            $info = getimagesize($handle->file_dst_pathname);
            echo '  link to the file just uploaded: [url="../usergallery/' . $handle->file_dst_name . '"]' . $handle->file_dst_name . '[/url]
';
            $imageurl = "http://site.net/c/usergallery/$handle->file_dst_name";
            $reg = mysql_query("INSERT INTO ibwf_gallery SET uid='".$uid."', imageurl='".$imageurl."', sex='".$userinfo[1]."', time='".(time() - $timeadjust)."'");

        } else {
            // one error occured

            echo '  file not uploaded to the wanted location
';
            echo '  Error: ' . $handle->error . '
';

        }

        // we delete the temporary files
        $handle-> Clean();

    } else {
        // if we're here, the upload file failed for some reasons
        // i.e. the server didn't receive the file

        echo '  file not uploaded on the server
';
        echo '  Error: ' . $handle->error . '';
    }
    

    echo "</p>";
