title: date_default_timezone_get(): It is not safe to rely on the system's timezone settings. ou are *required* to use the date.timezone setting
body: <p>I've just installed Symfony3, and apparently my "date.timezone" in php.ini was not good. So I found php.ini doing : phpinfo() in app.php, and I watched "Loaded Configuration File" to see where I could find the php.ini file.</p>
  
  <p>I change the value to "Europe/Paris", I saved and restart MAMP, but nothing. 
  Always the same message : 
  "Warning: date_default_timezone_get(): 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 the timezone 'UTC
    ' for now, but please set date.timezone to select your timezone."</p>
  
  <p>Actually I'm just trying to run "php bin/console server:run" .. </p>
  
  <p>So if some of you have an idea :)</p>
