The speed of light as we're discussing it is only mangled up with time as a recordkeeper, light holds a record of an event that happened at a certain time.
If you look through a telescope at a star you're looking back in time to how that star looked when the light you're viewing was sent on it's way... say 50 years ago.
If you could see how that star looks today using some new technology, it'd still take the light 50 years to reach earth, so you could think of it as looking at what we will see in our telescope in 50 years... today. It's not time travel but rather instantaneous information travel.
This sort of thing is not yet possible on a macro scale (I seem to recall that it has been done using quantum entanglement at a very small scale)
