Error: PHP - It is not safe to rely on the system's timezone settings.
You get the following warning when you run a PHP script:
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.
Solution
First find out your system's timezone. On Debian/Ubuntu, it's in /etc/timezone:
cat /etc/timezone
[email protected]:~# cat /etc/timezone
Europe/Berlin
[email protected]:~#
On Fedora/CentOS/RedHat, it's in /etc/sysconfig/clock:
cat /etc/sysconfig/clock
[[email protected] ~]# cat /etc/sysconfig/clock
ZONE="Europe/Berlin"
UTC=true
ARC=false
[[email protected] ~]#
Open your php.ini. On Debian/Ubuntu, it's /etc/php5/apache2/php.ini:
vi /etc/php5/apache2/php.ini
On Fedora/CentOS/RedHat, it's /etc/php.ini:
vi /etc/php.ini
Find the date.timezone line, make sure it is not commented out and has the correct timezone for your system:
date.timezone="Europe/Berlin"
Restart Apache afterwards:
On Debian/Ubuntu, you run:
/etc/init.d/apache2 restart
On Fedora/CentOS/RedHat, you run:
/etc/init.d/httpd restart
If you don't have access to your system's php.ini, you can set the default timezone at the beginning of your PHP scripts as follows:
<?php
date_default_timezone_set("Europe/Berlin");
[...]
?>
