The true "Universal Time"

[Aramil]

You can't when travelling at high % of (C). Time is relative, between you and an observer. In SC you "wormhole" to another system there is no dilation as you have not accelorated up to Lightspeed (C) to your destination, more punched a hole to somewhere and then travelled the short distance across (in seconds). With that sort of travel you could hold earth time everywhere, with ships/bases syncing and correcting every time you docked (maths wise they know where you started, where you visited, how far and fast you traveled, and where you are now) so with enough (would not have to be a lot) traffic from various places it would be easy to keep a standard "earth time" for commerse / timing of jobs/missions, etc.

Which would allow systems to keep a local measure of time (should they wish or need to) internally for day/night cycles, local system events, but also stay connected to the markets and shipping.

Traveling at high C % for long times can have massive implications for the perception of time for both the subject or observer, but in SC we are not, from an observers point of view, we dissapear from one place and appear somewhere else seconds later.

In short: with any form of travel where you can (almost) instantly move from one place to another, without having to accelorate to (or around) the speed of light, means you can easly keep a "universal time" as you do not suffer from any time dilation.

Isn't the thing you just described jumping via the wormholes? But what is with quantum travel? You spool up your drive accelerate and travel or is that again some space deforming travel system? And is cruise speed fast enough to induce that time dilation?

You can quantum jump from standing "zero speed" and arrive at "zero speed" so From what I have read Quantum Drives Warps Spacetime around your ship, so no dilation.
The flight model notes say:

Once the Quantum Drive is active, the ship will quickly ratchet up the velocity to the 0.2c limit – short jumps might never get going that fast – with the ship itself experiencing relatively little acceleration.

So i would say that the Quantum Drive creates a "Quantum Distrotion Field" around our craft making it's local space relative while the "exterior of the bubble" it's self is not. very much in the same way people in star trek and can walk around and function normally while travelling at "Warp".

If the quantum drive did not keep your local space relative you would not be able to do anything while travelling as everything towards the front (ie direction of travel) would blueshift (ie move into the blue spectrum of light and move closer together (narrowing of field of view)) and everything behind you would redshift (ie move into the red spectrum and spread out widening of field of view)).

At cruise speeds, Our ships are fast but not that fast, nothing to extreme that a sync to a local station/beacon could not solve.(for "earth time").

OK I understand that. But what does it have to do with timekeeping? I mean I was talking about instant transmission from an atomic clock to the ship so it can keep the time correctly (because of the relativity of time to speed thing). I wonder though if the same thing would happen (that the faster you travel the slower your time compared to the other slower traveling clock).

Keeping an atomic clock on your ship without adjusting for your current speed wouldn't even work. They have said quantum speed is 0.2c. So with a little fun math your atomic clock would be off by 28.8 minutes for every day spent in quantum travel.

Transmission has the problem of how far from source you are. I guess the UEE time officials could carefully calibrate each comm relay and as long as you have signals from 3 your ship could calculate the latency. Outside of that it would have to be up to the ships computer to keep time adjusting for relativistic effects and just re-sync when you are in a populated system.

I agree with the maths, but as "The flight model notes" state that "with the ship itself experiencing very little acceleration" means that the ship is held relative and so "spacetime" is not dilated, anything travelling at 0.2C within the "quantum field" should allow time to flow normally as it is not travelling at 0.2C, it is held relative and static within a "bubble" traveling at 0.2C. Think of the quantum drive as distorting the spacetime around you, but importantly not you.

When you throw a ball up in the air inside a train traveling at 60Mph it does not imediately slam against the back wall of the carrage at 60Mph, because it's motion and flow through spacetime is relative to the carrage and not the outside world.

Spacetime is very odd (complex) at times, but for the Quantum Drive to work without massively accelerating the ship it must build some sort of field/distortion/"container" for the ship to travel in, which holds a slice/bubble of relative spacetime inside. So a clock in "relative" spacetime (on a station) should read almost exactly the same as one "held relative" (on a ship) inside the moving Quantum Drives field, as neither has dilated due to spacetime distrortion.

Sorry I am trying to simplify a very complex set of rules, that Einstien himself said theoretically would allow relative close to C and FTL travel, without all the spacetime dilation.
