Symfony 2 error timezone

  Symfony 2 error:
  ======================
  [Symfony\Component\Debug\Exception\ContextErrorException]                   
  Warning: date_default_timezone_get(): 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 misspelle  
  d the timezone identifier. We selected the timezone 'UTC' for now, but ple  
  ase set date.timezone to select your timezone. in /Users/amonmoce/Document  
  s/Web/www/ZakafricaProject/vendor/monolog/monolog/src/Monolog/Logger.php l  
  ine 233 
  
  ====================
  Solution:
  I just went to the indicated file and I added the 2nd line ...
  if (!static::$timezone) {
        date_default_timezone_set('Asia/Taipei');
           static::$timezone = new \DateTimeZone(date_default_timezone_get() ?: 'UTC');
      }

Thanks for your contribution.
