Mini, This is an ongoing "SYNDROME". The last days has come and gone in the first century. Jesus was talking about the last days for Jerusalem and the end of that ( Jewish ) system of things. Remember, Jesus talked about more than one system of things. He spoke of systems of things to come, no date given for these other systems of things.
However I am a skeptic when it comes to hearsay words of Jesus. Misqouting Jesus is the thing that belief systems are popular for, each has it's own take and interpretation based on their own belief system as to what Jesus said and what time frame it applies to.
Every generation has had its last days syndrome. Just taking a look at the Watchtower Society's Last Days syndrome that has lasted for over 100 years ( that we have personally been involved in ) is an example of this.
