You should explain in more detail what you're trying to accomplish.

I want to make use of 'global logic' in my controllers (and maybe even have access to it in JavaScript). The logic would be for a 'made up date system', that's used for a game. So all the month and day names are made up and they don't follow the 24 hour, 7 day, 12 months thing.

I have not made the logic yet, but I think I will have an epoch that's based on the Unix timestamp. I can than substract the current time from the epoch and use the remaining seconds to do my calculations.

For those calculations, I want a 'global' class.

I.e.

<?php
/* Mock up!!! */
class GameTime
{
   public $months = array('Aburtei', 'Danai', 'Guura', 'Juunnu', 'Kuro', 'Serai', 'Vendrei');
   public $days = array('etc');
   private $epoch = 1398173634;
   
   public static function getMonth() 
   {
     /* Calculations etc */
	 return 'Guura';
   }
   
   public static function getDay() {}
   public static function getYear() {}
   
   public static function getFormattedDate($timestamp = time()) 
   {
     /* Calculations etc */
	 return 'Tuesday, 22 Guura, of the Year 1';
   }
   
   public static function getDateInFuture($timestamp) 
   {
     /* Calculations etc */
	 return self::getFormattedDate($timestamp);
   }
   
}
?>
