>You wouldn't experience time dilation in this scenario, because the ship itself isn't actually moving faster than light speed.

Time dilation occurs at speeds far less than the speed of light. For instance GPS satellites and jet planes experience measurable time dilation.

I am very curious about the time effects of such a drive. Does the ability to warp space using such a device necessarily include the ability to warp time? Is it possible, within a frame of reference, to locally reverse the arrow of time and thereby reverse entropy within that pocket?

>A beam of light inside the warp bubble will still travel faster than the ship, for instance.

But that beam of light seen from outside the bubble will appear to travel faster than the speed of light.

"Time dilation occurs at speeds far less than the speed of light. For instance GPS satellites and jet planes experience measurable time dilation."

Sure, but I think (?) the original question was asking about time dilation in the massive sense: i.e., you go on a round trip to some distant point in space and return, and it's only been a few days for you, but a few hundred or thousand years have passed on Earth. That sort of time dilation.

That sort won't occur with an Alcubierre ship. It's my understanding that the ship isn't actually moving at all inside the bubble -- or, if it is, it's moving extremely slowly.

That depends on what the outside of a warp bubble looks like. Since it's bending space all over the place, it may not be observable from outside.
