default timezone not supported???

[Michael Pay]

Hey y'all, I've been getting this error message ont he setu

Major problems have been detected and must be fixed before continuing:

1. Your default timezone is not supported by PHP. Check for typos in your php.ini file and have a look at the list of deprecated timezones athttp://php.net/manual/en/timezones.others.php.

I have already tried a bunch of variations on the date.timezone line and it still shows the error. Any tips?
