title: Warning: require_once(): It is not safe to rely on the system's timezone settingserror in PHP
body: <p>I am trying to install a open source PHP application IIS; after installation I am getting the following error:</p>
  
  <p>Warning: require_once(): It is not safe to rely on the system's timezone settings. You are <em>required</em> 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 'Asia/Kolkata' for '5.5/no DST' instead in D:\Inetpub\wwwroot\dotproject\lib\adodb\adodb.inc.php </p>
