Supercruise isn't technically passing C. In your localspace bubble, you aren't even close to approaching C. The bubble itself, which is translocated spacetime shifted through gravitational waves, exceeds C by orders of magnitude, but relativity is concerned about your localspace speed. You're moving space, instead of moving within space. Thus you mitigate length contraction, special relativity, lorentz factors, etc.
The big controversy is how fast does gravity propagate. Some studies have tried to argue it propagates at C while others argue otherwise. I say we simply need to look at the rate of expansion of our universe to see that it can exceed C.
This paper has lots of good info. Doctor Sonny White at NASA is a smart guy.

According to the movie lol 
Lets just say "its complicated"
But if FSD's work by making space move around the ship, then basically moving a bubble of space where you are within, then you technically don't travel faster then light, and at least from my understanding regardless of how fast you get from a to b via this method, your time would still be at least partially in sync with the earth, though it would wary with the gravity of the various planets and such you ended up being on and visiting, it wouldn't simply be you feel 10 minutes have passed and 1000 years would have passed either, which is what it would be sort of like if your ship itself actually moved as the speeds elite ships do, that said, moving faster then light isn't possible, so you would max out somewhere near 0.99c which would still be very slow. Universe wise.

Hey, it's all relative.
They are all dead dave, dave they are....
Supposedly, the FSD avoids relativistic time dilation by having the ship actually travel at its normal speed (~300 meters/sec) inside a bubble of compressed space.
If you can go 300 m/s, but also you can reduce the 10 millimeters in front of you to 1 millimeter, then you are effectively going 3000 m/s. Even though your effective speed is very fast, your speed in your own frame of reference is still much slower than light, meaning no time dilation.

Well, it's not like ED is actually realistic anyway so ...
Actually Elite Dangerous' method of travelling faster then light is one of the few realistic methods that exist that don't break science as we know it...just so you know. Since nothing is actually moving faster then light.

Ok ........
Look at the bright side: buy cheap, unaged liquids, go on a trip, and sell them with certificates when you return. No matter how it tastes, you just produced legit three yo rum in half the time.
What do you need friends for when they decline to cross the galaxy with you anyway? Relatives? Space trucking isn't really the profession for the domestic sort. Send pictures.

Not representative of anything other than your sensors not being able to make sense of things.
Travel time in hyperspace has nothing to do with distance, and even short jumps would be the equivalent of vastly higher SC velocities than any four figure multiple of c.
Yup. It's the ship basically going "Well, do you have a better idea? I sure as hell don't know. Look, you crack open some Chango Gin and I'll just sit here and throw numbers at you."

Which is stupid beyond belief.
It's like everyone forgot how to program in the year 3000.
Me, I'd just turn the damn thing off when I enter hyperspace.
SC is the bubble of space your ship is in moving, not the movement of your ship. Your ship has no velocity, no inertia, etc, in SC.
This is all sorta implied by frame shift drive.
The universe appearing to expanding faster than c is not at all the same thing as gravity propagating faster than c.
c is a constant of travel through space-time, not a constraint on space-time itself. Extremely rapid increases in the dimensions of space don't change c or anything dependent on c.
There is no evidence to suggest that gravity can propagate faster than c, but we will likely have to wait for a relatively nearby supernova to have solid empirical verification.
I'd rather leave it running and have the sensors try to lock on to celestial bodies and calculate an apparent velocity, even during situations where it should be impossible.
Afterall, I want to be the one to decide whether I'm in hyperpace or not, not the computer. The more separate telemetry sources you have available, the easier it is to spot anomalies.
It's physically impossible to travel greater than the speed of light. In game, the warp drive/alcubierre drive warps space so that while your spacecraft is technically motionless in Einsteinian/Newtonian physical terms, the space between your destination and you is bent so that your "speed", or rather rate of decrease of distance between you and your destination, can be greater than c. Also, this is in play when you frame shift at less than the speed of light, no time dilation. Then there are black holes, and spending time near high gravity objects like stars, which I'm assuming that the warp bubble also negates dilation here (which is why there is noticeable strain on the maneuverability of your ship near multi-solar mass objects). The only real plot hole in the game is when you drop out of frame shift near such an object - then you would experience dilation the degree to which depends on your distance and the magnitude of gravitational field.
You'll notice that your thrusters are off unless you're out of frame shift, so it's not traditional motion. There's also a universal clock in every spaceport you dock at that is shared with everyone else that is always constant with everyone else.
The universe expanding faster than c is simply your frame shift drive, except on a extreme scale - the fabric of space stretching. Also, if you are in a car that goes 90 kph in one direction, and someone else goes in a car 90 kph in the opposite direction, you are moving 180 kph relative to the other guy without going 180 kph relative to your last position. In more complex terms, think of stretching space as an infinitely expanding balloon in which the velocity between any point on the balloon and its previous location cannot exceed c. But this also means the two points on the opposite sides of the balloon will have velocities of 1.9999999....c maximum relative to each other. And even then, these two examples aren't perfect, as stretching space can't be directly equated with motion as we know it.
As for "gravity propogating faster than c", all matter has been present, more or less, since the beginning of the universe, and its gravity has too. The gravitational field of your body/random molecule of oceanwater/Earth/Milky Way/any collection of matter in the universe extends to the boundaries of the visible universe and beyond, except its influence billions of ly away on the other side of the universe is so weak there as to be negligible. This is disregarding the extremely minute portion of matter that has been converted into energy by stars/black holes, atomic bombs, the A class reactor on your Anaconda etc. a la e=mc^2, as well as hawking radiation releasing parts of a black hole's mass. And actually even energy has gravity, so the universe's total gravitational field has been pretty constant since the beginning of time.

Though it is correct that two reference systems show symmetry in respect to the passing of time, will say one sees the others time pass slower, there are real consequences (according the theory of Albert Einstein) once one reference system is exposed to changes of speed (be it slowing down, accelerating, stopping and turning back). So in those cases the predictions are that this reference system indeed is exposed to slower passing time in respect to the other and when both meet, the effect will be obvious (Twin paradox https://en.wikipedia.org/wiki/Twin_paradox ).
I have also seen Interstellar and in my opinion there are logic holes of the size of Garganta in the movie, but it was great that such a topic and its physics were treated in a movie.

It was a big bag of turd, started off decent, just like Contact with old Jodie Foster did......
And then it turned into a big pile of biological waste, just like Contact with old Jodie Foster did....
I mean the alien was her dad?
And the aliens put him behind the book case and made his watch tell them how to fix everything.... Using Morse code or something!!!!!
Pfff!
It was as anticlimactic as a Friday night with my wife after I've drank 30 cans of Stellar!
Far from insterstellar
See what I did ther?
Yaaaaaarrrr jim lad.
