I am trying to install Zen Cart on a Windows 2008 local server. MySQL and PHP both installed without any problem. I start the application localhost/shopdevel and the Zen Cart installation page displays. Then when I click on the Click here to begin I get the following error.

ERROR: date.timezone not set in php.ini. Please contact your hosting company to set the timezone in the server PHP configuration before continuing
I get the PHP info and the timezone is set to America/Chicago.

What am I doing wrong?
