In Noah's time, God said, ". . . I have determined to make an end of all flesh; for the earth is filled with violence through them; behold, I will destroy them with the earth" (Gen. 6:13). This clearly indicates that it was the time of the Last Days.
Jesus' time was also the time of the Last Days; for this reason, Jesus said that he had come to judge and destroy the sinful world and build the world of the ideal of creation (Matt. 5:48), John 5:22).
When the Lord comes again it will also be the Last Days, for it says in Luke 17:26, "As it was in the days of Noah, so shall it be in the days of the Son of man."
