How to Solve the Warning: date() [function.date]:

If you have received a top page error similiar to the below, here’s how you correct it.

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.

OPTION 1 – PHP.Ini – Define Server Timezone

Add this to top of your root domain php.ini file.

php_value date.timezone “America/Los_Angeles”


OPTION 2 – Inside PHP Files (you will need to set this for ALL php files (not recommended in most cases)

<?php
date_default_timezone_set(‘America/Los_Angeles’);
?>
