In a letter published on August 8th, Fay was wondering how people could survive a seven year tribulation.  Decades ago I read a prophecy book; I do not remember the title or author. It speculated that the fourth trumpet in Revelation speeds up the earth's rotation, shortening the length of the day by one third.  Since the Bible mentions day counts in the Old Testament, I do not think the number of days will be reduced.
