If you are seeing a blank screen during install or see errors about the timezone not being set, example:
Description: 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. We selected 'America/New_York' for 'EDT/-4.0/DST' instead
Please add the following line to your php.ini or have your host do it if you do not have access:
date.timezone = America/New_York
You can set the timezone to your timezone, the one provided is an example. Make sure to restart your web server after making the change in the php.ini for changes to take affect.
