Re: Is everything before the destruction of the kelvin exactly the sam
Anyway, if you prefer the Prime Timeline to be immutable then you can adduce as evidence the fact that Futurespock's ship uses stardates in the Abramscerse format and not the established xxxxx.xx format.
I'm not sure how relevant that is. Is it inconceivable that stardating conventions changed or became open to multiple variants sometime between 2379 and 2387?
