My assumption at this point is that the stardates in SNW are a targeted attack on me specifically. The one way to resolve it is for me to challenge Akiva Goldsman to ritual combat with the lirpa, but he won’t reply to my emails.
They work just like they did in TOS, where everything is made up and the stardates don’t matter.
For real tho. The TOS season 2 writer’s bible (which you can find online) basically says the stardate number is a complex calculation that depends not only on time, but your location in the galaxy. I would not be surprised at all if the showrunners/writers are aware of this and are purposely doing it as an homage.
