Does Santa deliver presents?

He starts by delivering presents at the International Date Line and travels west following the Earth's rotation around the sun. By doing that he gains many, many extra hours of time. Children are actually waking up and opening presents while Santa is still delivering!

How long would it take for Santa to deliver presents?
