Testing "expired" turns for GKTurnBasedMatches

Is there a better way to test expired matches using Game Center other than wait 7 days ( minimum expiration interval ) and see results? That is incredibly time consuming especially if you find bugs in your code. Does Apple provide anything to help with this?

To clarify, can I specify a turnTimeout value smaller than 7 days in the following call?

func endTurn( withNextParticipants nextParticipants: [GKTurnBasedParticipant], turnTimeout timeout: TimeInterval, match matchData: Data, completionHandler: ((Error?) -> Void)? = nil )

Note: my game is a two player game.
