Yeah, I see, the API is just total shit. First passing the TSF and then
calculating it to override? Why not do the calculation outside the API
always?

The TBTT calculation does intentionally not use the mactime value.

Synchronization uses the time in local TSF units and the exact same time point in peers TSF units at the time of sending/receiving (mactime field). The TBTT calculation uses the time of NOW, i.e. the current TSF after possible delays in firmware/driver/rx-handler which may have outdated the mactime field.
