Yii设置日期默认时区错误

Question

After creating new webapp with its name. I get this error now.

PHP warning

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 the timezone 'UTC' for now, but please set date.timezone to select your timezone.

After got this result I wrote this to config array:

'timeZone' => 'Asia/Tehran',

and to index.php:

Yii::app()->setTimeZone("UTC");

But that does not change anything and the problem remains unsolved.

My default system date is :

Tue Dec 31 14:11:49 IRST 2013

php.ini :

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

; 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

Answer 1

You can also use this if you do not want to touch your php.ini file

date_default_timezone_set("Asia/Tehran");

OR

ini_set('date.timezone','Asia/Tehran');

Update
You can also use

ini_alter('date.timezone','Asia/Tehran');

But do not forget to call it before calling any date function.
