in order to survive time travel you would need some form of space craft. I say this because of the many variables regarding motion. The earth is rotating, and revolving around the sun. The solar system is revolving around the center of our galaxy. If you were able to travel through time, you would end up at the same point were you left from, in the three dimensional planes of space. the earth would be displaced. You would probably end up some where in space. In order to survive and get back to earth, you will need a space craft, and a very fast one at tha, because of the uncountable light years away you will need to catch up with earth.
