Brotherdan,
God didn't tell us when the end of this world will be ,
but through Biblical chronology found in inspired prophecies, He tells us when certain events - taking place within His people, during the "latter days"- will be , I mean, events that marks Christ's "coming"
and around 2012 a certain event will be , that is , the "70 years of Babylon" will come to end ,
and His worshipers with "spirit and truth" , who were/are prisoners in Babylon (and at the "Daughter of Babylon" ) will be made free and gathered in "one flock" under the Jesus Christ authority
see Jeremiah 29:10-14
for those "studious" Christians I recommend this theme
