Earth Hive gives a launch date for the Benedict and K-014 as April 5 2092, and many of the other books mention how many years since the Alien invasion (Genocide for instance gives a date of being 18 years after). So MOTS being in 2124 fits in that regard, but Navarro doesn't mention the Earth invasion instead talking about characters growing up on Earth when the invasion would be happening and something called the 'Homeworld Wars'.
