Доброго времени суток!
Получаю сообщения следующего типа и не знаю как исправить. Посоветуйте решение проблемы.

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 'Europe/Helsinki' for 'EEST/3.0/DST' instead in /var/www/html/drupal/modules/token/token_node.inc on line 49.
