Again, just because time is 'present' doesn't mean that 'time is a synchronization primitive'. Programs execute over time, but synchronization is not fundamentally about when things execute, it's about the order that they execute. The order is what is important, not specific time coordinates or specific timing. Just like cars merging, where they go in absolute space is not the fundamental concern, it is where they are relative to each other so they don't overlap. Synchronization is about serializing events if they have overlap in the data they affect.
