Total BS. Time as we know it is nothing like Mayan time. From wiki:
The Mesoamerican Long Count calendar forms the basis for a New Age belief, first forecast by José Argüelles, that a cataclysm will take place on or about December 21, 2012, a forecast that mainstream Mayanist scholars consider a misinterpretation, yet is commonly referenced in pop-culture media as the 2012 problem.
“For the ancient Maya, it was a huge celebration to make it to the end of a whole cycle,” says Sandra Noble, executive director of the Foundation for the Advancement of Mesoamerican Studies, Inc. in Crystal River, Florida. To render December 21, 2012, as a doomsday or moment of cosmic shifting, she says, is “a complete fabrication and a chance for a lot of people to cash in.”
