It’s already December 21, 2012 in the Philippines.
You have to wait until the sun first rises on the winter solstice and strikes the pyramids one after another around the world thus activating the the time generators and microwave generators that are hidden within the pyramid walls creating a star gate for the black hole from Orion to appear and disrupt the earths magnetic fields. DON'T CHA KNOW!
I think it would be based on the time zone of the Yucatan where their main pyramid is and that is US central time. I know that because I was there and didn't have to change my watch. Yes, I just checked and it is central time zone. The time there right now is exactly my time in Texas, so it definitely is central time zone.
