1. Time travel to the past does not CREATE new timelines -- it merely reveals parallel timelines for the first time (which, to the time traveller, would appear to be the creation of a new timeline, since its existence was not previously known in his own Universe).
2. Time travel to one's own future is impossible in any scenario.
Consider this: You travel one minute into the future, meet yourself, have a two-minute conversation with yourself, then return to your present. How many of you are there now?
Or this: You travel one year into the future, meet your one-year-older self, then shoot yourself in the head, committing suicide. You obviously won't live to be one year older, so the future you were just in with your older self obviously can't be your own future. But it can't be anyone else's future, either, since in to timeline would you both live to be a year older while meeting yourself from the past and watching your younger self commit suicide.
Therefore, the only way to alter timelines is by travelling to the past; travelling to the future -- yours or anyone else's -- is impossible. (However, a time traveller FROM the future can take you back with him, but that would mean you are from a divergent timeline he "created," not that he is from YOUR future. Spontaneous travel to the future is logically impossible -- the time travel must be initiated FROM the future.)
