You know what, that is still confusing especially when you bring it up to casual viewers. They don't have to do this timeline1/timeline 2.
The first six movies are part of 1 timeline, it doesn't matter if the Sentinels Project was secretly in the works during the original trilogy.
They don't have to make this confusing by telling us there's already 2 timelines even before DOFP starts rolling.
