So if Starfleet Academy is on Earth here that suggestmy s it might not be 32nd century... unless they moved the Academy back there very quickly after Earth rejoins the Federation.
Throw away line in the first episode:
"In the long tradition of the Federation, Starfleet Academy's location was always this place here. On Earth. With Earth now part of the Federation again, we are thrilled to build on this new found relation of mutual trust and friendship by re-opening the new Academy on its old foundations."
Or something like that.
What is weird though.... with so many worlds in the Federation and thus most likely countless of cadets, it's insane to think there is only on physical academy. In the 23rd and 24th century there were most likely many sites throughout the Federation.
