Every time you set up a server for PHP, especially in PHP version 5.4, You would get something like this:
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 ever encounter this, a quick solution is to set your timezone on your application using date_default_timezone_set
For me, that would be ‘Asia/Manila’
A long term solution so you won’t set that function on every application on your server, will be to set in on your
date.timezone = 'Asia/Manila'
