Well, Hashes are unordered by definition, but as long as we declare  
an order it's doable:

 >> time = {
?>   :year => 2003,
?>   :month => 03,
?>   :day => 24
 >> }
=> {:month=>3, :year=>2003, :day=>24}
 >> Time.local(*time.values_at(:year, :month, :day))
=> Mon Mar 24 00:00:00 CST 2003

Hope that helps.
