Why do some people say moving faster than light would mean you travel back in time?

Are those people just misunderstanding some concept in relativity?

This idea is born of a thought experiment Einstein is reported to have performed.  Simply put, if one were traveling away from a clock face at the speed of light, the appearance of that clock face would not change because you would be traveling at the same speed as the photons that were reflected off of it.  If you were to then accelerate, you would catch up to the photons that were reflected *before* you achieved the speed of light.  In essence, you would arrive at an earlier time because what you are observing now isn't what is happening now, it's what happened before.  When that clock ticks forward another minute, you will never see it because you are moving away from it at the same speed as the light that bounced of it in the new minute.

Ok maybe not so simply put...
