"phpinfo(): It is not safe to rely on the system's timezone settings..."

Question

While running a php installation script for Blue.box (front end to FreeSwitch PBX), I get this error about a timezone failure.

Then I start digging. I'm not sure what is going on at this point. But here is what I have:

I created an info.php file in my public_html directory that contains a single line:

And I get this error and output

Warning: phpinfo(): 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 'America/New_York' for 'EDT/-4.0/DST' instead in /home/0default/public_html/info.php on line 1

    date.sunset_zenith  90.583333   90.583333
    date.timezone   America/New_York    America/New_York

I created a file /etc/php.d/timezone.ini with the following:

[root@mercury php.d]# cat timezone.ini
; default time zone
date.timezone='America/New_York'
[root@mercury php.d]#

I'm able to change timezone to America/Los_Angeles (for example), and after apache reboot the "date.timezone" field changes correctly.

But I still get the error.

Any ideas?

--- Additional note ---

If I change the /etc/php.d/timezone.ini file:

[root@mercury php.d]# cat timezone.ini
; default time zone
date.timezone='America/Los_Angeles'

I can cause a change to the info.php output:

--- Additional note ---

For those who are learning (as I am), several .ini files are loaded. In the info.php output:

Configuration File (php.ini) Path   /etc
Loaded Configuration File   /home/0default/etc/php5/php.ini
Scan this dir for additional .ini files /etc/php.d
Additional .ini files parsed    /etc/php.d/curl.ini, /etc/php.d/dom.ini, /etc/php.d/fileinfo.ini, /etc/php.d/gd.ini, /etc/php.d/imap.ini, /etc/php.d/json.ini, /etc/php.d/mbstring.ini, /etc/php.d/mysql.ini, /etc/php.d/mysqli.ini, /etc/php.d/odbc.ini, /etc/php.d/pdo.ini, /etc/php.d/pdo_mysql.ini, /etc/php.d/pdo_odbc.ini, /etc/php.d/pdo_pgsql.ini, /etc/php.d/pdo_sqlite.ini, /etc/php.d/pgsql.ini, /etc/php.d/phar.ini, /etc/php.d/snmp.ini, /etc/php.d/sqlite3.ini, /etc/php.d/timezone.ini, /etc/php.d/wddx.ini, /etc/php.d/xmlreader.ini, /etc/php.d/xmlrpc.ini, /etc/php.d/xmlwriter.ini, /etc/php.d/xsl.ini, /etc/php.d/zip.ini

The first one loaded is /etc/php.ini, then the "loaded configuration file", then the "scan this dir" files.

So for example, one should be able to create a number of php web sites in different default timezones. Set the master default in /etc/php.ini, then allow each of the web sites to have a different time zone as identified in the "loaded..." section. Then, if one is concerned about any overrides, the master can again override with the /etc/php.d files.

I've tried changing the "date.timezone" in each of the three locations, and successfully change the date.timezone as displayed by the info.php... but it does not modify the "Default timezone" value, which is the value that is causing the error.

Another note, the .php script that I am running is actually Blue.box, a front end to FreeSwitch. So... I am hesitant in changing that .php script.

Solution 1

You have 2 options:

1. Call this function date_default_timezone_set() before using any date functions. E.g. date_default_timezone_set("America/New_York");.

2. Edit the php.ini file usually located at /usr/local/php/php.ini and change the date.timezone entry. Here is the list of supported timezones.

I solved this problem by find which php.ini your server is using. First, you should make a page show phpinfo(), and you visit the page, you can see the normal infomation; Second, find "Loaded Configuration File" in the page, you should see what php.ini file your server is using. like:"/etc/php.ini"; Third, you edit the certain file in your server, like: date.timezone="Asia/Shanghai" then restart the server. Done. Good luck.
