This is the official answer of jw.org about 100 years of 1919.
The style of the talk is like the "Tell us when will this occur" part at the 1993 convention, about the "Sun, moon and stars" in the time of the end.
There was a lot of speculation about the real purpose of that talk in 1993. Change "was in the air", was the feeling. And it was, just before the new generation doctrine in 1995.
Losch was just reading a talk written by some one else. I think it is written by David Splain or Herman van Salm, the Dutch helper of the GB, because of the long list of European historical persons claiming to know the date of the End.
Curious!
