When Santa is first ready to take off, Nigel tells him to start his flight in New Zealand, in the easternmost time zones, and work his way west as the time zones progress. That notion is discarded for the rest of the movie as Santa spends Christmas Eve in Milwaukee, Wisconsin. Nigel, Santa, and the Foxes work on the premise that they need to get everything ready for Santa by midnight Central Standard Time (in Milwaukee), while Christmas Day is already almost over in places like New Zealand.
