    The Theory of Relativity assumes that all observers see time as a constant, but perceive that the clocks held by others may run at a different rate. Hence it's possible under general relativity for a person to leave earth and come back 100 years later but that person has aged only a few years (this is the twin paradox as Tut pointed out). Is that time travel? I think not - there is no mechanism that would allow a person to go backwards in time, which at least in popular culture is what "time travel" is all about.
