When they discovered the error due to no zero year they moved Jerusalems destruction from 606 to 607 rather than alter 1914.
Thank you for highlighting this. Once I learned this particular detail, the entire "607 Issue" became so simple, for me. The blatant dishonesty involved in changing 606 to 607, simply to allow 1914 to coincide with the beginning of WWI tells the entire story, IMHO. They're a bunch of liars and they don't care about what is actually true. They blindly adhere to the concept that God leads them -- in spite of all available evidence.
