The thing that most annoyed me about the reboot of the canon after the buyout was that the new system didn’t introduce more time between AotC and RotS and between TESB and RotJ but instead kept the bizarre compressed timeline.
They never made it explicit, but they also never really stated an official timeline.
Based on Cut’s family, and how old his kids were in The Deserter, there could even be more time for the war than 5 years.
