Seems like I've heard something about that. The trouble is that which exact year would it be? From what I understand that Jesus would have been born several years BCE because King Herod died several years BCE, and King Herod is an important figure in the nativity narrative. So if you set your time machine for 33 CE you'll have missed the crucifixion.
