Not surprising if this is real. A lot here have speculated about not if but when they will drop the 1914 date.
Waiting until 2019 makes sense because it is now 100 years since the last date tied to 1914, the war in heaven, the casting down of Satan and finally the establishment of pure worship on earth in 1919.
After 100 years with nothing to show, even the gb must realise they are pushing it.
Edited to add, I have often wondered if they would consider switching their equations to the secular date of 587 for the starting point of the end time prophecies. This would buy them another 20 years. I'm sure they could come up with something significant occurring in 1934.
