The appearance of the D once again brings me back to the question - is each reality also in the year 2382, or is there a temporal differential that randomly varies?

There are a couple other instances begging this question:

• Captain Tersal is wearing a TNG-era uniform. It wouldn’t be much of a stretch to just say the uniform was never retired in her timeline and are intended to be kept largely the same like the monster maroons, but it still presents a possibility.
• Boimler is able to read about alt-Boimler’s missions on the alt-PADD. Does this mean alt-Boimler’s timeline is a bit ahead, or is the PADD somehow maintaining its connection with the alternate timeline?

I might also add that it being a Galaxy Class Enterprise alone does not mean it is the D - we only know it’s the Enterprise D because of Ransom calling it “the purple D”.
