Second Coming; Year of Jesus’ Return 

On Feb. 14, 1835 Smith said in HC 2:182; “…and it was the will of God that those who went Zion, with a determination to lay down their lives, if necessary, should be ordained to the ministry, and go forth to prune the vineyard for the last time, or the coming of the Lord, which was nigh—even fifty-six years should wind up the scene.”

Matt. 25:13; “Watch therefore, for ye know neither the day nor the hour wherein the Son of man cometh.”

That became a false prophecy in 1891 in addition to what Jesus said in the verse above.
