Given the manipulation of time througout the series, the time wound in Skyrim and the whole Warp in the West business can time travel really be discounted. However, given that the Warp in the West didn't involve time travel and the time wound only enabled to you to view, not directly affect events, I can't really see time travel happening. Unless there's a third Numidium, but that would just be ridiculous.
