Проблема на сайте... - Joomla 1.5: Общие вопросы

Доброго времени суток всем!
Примерно месяц назад сделал проект, и вот только вчера на сайте заметил что вылезли некоторые я так понял ошибки, или может быть определённые не доработки. А до этого этих не доработак не было...

Вот такого рода:

Warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Samarkand' for 'UZT/5.0/no DST' instead in /var/www/vhosts/mippodrom.uz/httpdocs/libraries/joomla/utilities/date.php on line 198

А так выглядит в админ панели в меню "Менеджер материалов"

Может кто подскажет что нужно мне сделать, чтобы эту ошибку устранить!?  Ссылка на проект:  http://mippodrom.uz/
Заранее благодарю!

А если в админке пояса часовые поменять?

Пробывал менять, всёравно не помогает...

Присоединяюсь. Такая же беда. Кто как исправил ее?

или выключить отображение ошибок или назначить часовой пояс в php.ini
