Timezone settings problem in codeigniter

[eluser]abdel[/eluser]
Yes.. I restarted the Apache server. Currently by php.ini have:

Code:

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = Asia/Dubai

; http://php.net/date.default-latitude
;date.default_latitude = 31.7667

; http://php.net/date.default-longitude
;date.default_longitude = 35.2333

; http://php.net/date.sunrise-zenith
;date.sunrise_zenith = 90.583333

; http://php.net/date.sunset-zenith
;date.sunset_zenith = 90.583333

and in my config.php found at ci/application/config folder has:

Code:

$config['time_reference'] = 'local';

When I call a controller method which doesn't reference any model.. it simply works fine! If I create a instance of the model.. it stops working! I have nothing except this in my hello.php (Model)

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

    class Hello extends CI_Model {

        function __construct()
        {
            parent::__construct();
        }
    }
?>
