Brainfart follows:-There is no space and time, there is just spacetime. It's all the same. What was the centre of the universe in the beginning is now the edge of the universe, but there is also no outside of the universe in ways we can comprehend. So the question is not how to we travel in time, but how do we travel in spacetime.
When you look at distant stars and galaxies you are looking back in time - The universe doesn't look like this now. In fact it has never 'looked' like this, because each part of it looked like it appears to look at different times in the past, the further away, the further back in time you are looking.
We can travel in 3 dimensional 'space' by 'spending' time, we need to somehow find a mechanism to 'spend' one of the other dimensions to let us move between times instantaneously. This could be achieved by a wormhole, which would be a direct link between 2 points at a great distance, but I'm suspecting they would only be like 1 atom across and last for a billion billionth of a second or something, so you're probably not going to be able to drive a bus through.
So the answer is, I don't know.
