"They questioned Him, saying, 'Teacher, when therefore will these things happen? And what will be the sign when these things are about to take place?' And He said, 'See to it that you are not misled; for many will come in My name, saying, "I am He," and, "The time is near." Do not go after them.'"
— Luke 21:7-8 (NASB)
I am quite sure that not a year has gone by in my life, and perhaps not even a month, without learning of someone who is the latest to claim either that they are the Christ, or that they knew the precise date of His return. Jesus Himself says that one of the primary signs of His impending return is a rise in false Christs. The leader of the Moonies claims to be such, David Koresh claimed such, National Geographic followed such a claimant and his flock for a year in their New Mexico compound — the list is practically endless. I am sure that there has never been a point in time during any historical period when there have not been at least one of these posers, but the sign Jesus speaks of is quantity: "Many will come in My name". We are experiencing the same kind of multiplied increase which occurred at Jesus' First Coming.
