News flash there is NO difference.
Take a look at this answer to a question from a class I am taking:
I strongly believe the teaching of Joel tells believers that they are not in the last days (now) and that back in biblical times, the last days have occurred. I also believe that even though people proclaim that JC will return, soon, that he will not return for a WHILE on earth. However, we must be prepared for the return of Christ regardless of what people think or say or do who are trying to make us believe that he will return today or next year! The power of the Holy Spirit has changed me and worked through me by ministering to me and having me minister to others Online and in public places as well as private places.
Acts 2:17-21 says it all. We are NOT living in the last days!
Come on, even believers today are being deceived by others claiming to "know when Christ returns."
Matthew 24:36-42 NIV
 “But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father.  As it was in the days of Noah, so it will be at the coming of the Son of Man.  For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark;  and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man.  Two men will be in the field; one will be taken and the other left.  Two women will be grinding with a hand mill; one will be taken and the other left.  “Therefore keep watch, because you do not know on what day your Lord will come.
Hope this convicts you if you have been trying to figure out when Christ will return!
