If the world is going to end on Dec. 21, it had better hurry up.
On half of the globe, it's already Dec. 21.
At 5 a.m. in the Eastern Time Zone, the first part of the world - south Pacific - goes to Dec. 22. Other parts of the Pacific will still be on Dec. 20.
When it gets to Dec. 22, it will be too late Mayans.
