If they are mentioning, it means they are into something. Maybe dropping 1914 or another important date?
I know a brother that lived during those time, one of the few in my area, a die-hard elder who is always pushing the young ones to pioneer and not attending higher education. I think the witness from that era that are still inside have invested so much in the religion that they will never quit.
But probably it could raise some questions to the young ones. They're planning something I guess.
