"International Dateline" is the sixth episode of The Suite Life on Deck.
In a similar fashion to Groundhog Day, Cody tries to impress Bailey at their school dance, but he fails and finds himself stuck in a time loop while everyone is oblivious to what is happening. Cody believes the time loop is caused by fate giving him another chance with Bailey, but eventually realizes that lightning striking the ship as it crossed the International Date Line was what caused the time reversal, so he reduces the ship's speed to break the time loop. In the end, he still fails to impress Bailey but Zack helps him out.
