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.
If you are getting this error in any of your PHP projects, the fix would be to add the
date.timezone directive in your
php.ini like this:
date.timezone = "Asia/Manila"
before calling any date or time functions. Of course, you can set it to other supported timezones. You might need to restart your web server for the changes to take effect if you choose the former.
date.timezone directive existed prior to PHP 5.3.0, but was generally commented out that’s why it probably messed up your projects after updating your PHP versions to 5.3 (and mine too!)
