Time travel and FTL travel are the same thing.

If you travel faster than light, there is at least one frame of reference in which you time travel into the past.

Similarly, if you time travel into the past, there is at least least one frame of reference in which you travel faster than light.

This truth applies to any model of FTL travel or time travel, no matter how fast or slow you travel, no matter what fictional excuses you devise. It is an ironclad result of special and general relativity.

To coin a better phrase, it is neither FTL travel nor time travel. It is always space-time travel.
