Just the name "time travel" is a misnomer. Travel implies going from one place to another-time transfer is closer, but still implies movement. It is hard to get past that rate x the time, you end up with distance. Time shift would have to be transdimensional, or better yet, to be in a certain place to see everything at once, eternity in both directions. The closest I have seen to a description of something like that is John in the book of Revelation.
Kinda makes you want to duct tape your head to hold it together.
