If you have not set a timezone you may get an error from php. This can be resolved by:
- Finding where the php.ini is stored by running
php -i | grep 'Configuration File' - Finding out your timezone from the list on this page: http://php.net/manual/en/timezones.php
- Editing the php.ini file (or creating one if it doesn't exist)
- Adding the timezone to the php.ini file e.g., adding the following line:
date.timezone = "America/Los_Angeles"
