Description:
------------
Using date_default_timezone_get() without having set a timezone before, produces an error:

"It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. We selected 'Europe/Paris' for '1.0/no DST' instead".

I want to check the current timezone and this should be the correct function for it. I want to get a result to work with

Reproduce code:
---------------
<?php
echo date_default_timezone_get();
?>

Expected result:
----------------
Get an empty string, like with "ini_get('date.timezone')"). Also false or null would be okay.

Actual result:
--------------
Error message.
