Or is this just one more thing the Watchtower Society is using to confuse the flock so that they will feel helpless aside the Society? I think so. They have enough other tricks: the Urim and the Thummin, the deals between God and each of His Bible servants, the multiple classes that mean almost the same thing and virtually everyone in one class is in all of them, and so on. My guess is that they just want to confuse people so they will be afraid to look outside the box for the true answer.
As I see it, Jesus still hasn't come at all. The year 1914 was just as important as 2007--no more and no less. They failed to mention 1860, when the Civil War was started. They didn't mention 1941 when Pearl Harbor was attacked. They didn't mention 2001 when the World Trade Center was hit by the planes. They didn't mention any period around or leading out of the Dark Ages. And 1914 is getting out of date, so they need anything to further confuse the flock into disregarding that blunder. Anything to keep the scam going longer.
