You can travel forward in time if you go close to light speed and take a nap in a hibernation chamber while doing it. Doesn't matter if relativity causes it. Time for you slows down and keeps on moving for the rest of the universe. If that's not time travel then nothing is.
No, you are a time-rider is all. Time travel as a term indicates that you leave the time continuum at one point and return at another. Your biology does not allow you to do that. You are trapped in time always riding the short duration of human life. You might appear to extend that time by travelling at near light speed, but it is not time travel.
You really are wasting your life arguing.
