Appears (as in observed). However, you'll hear the many of
the modernist crowd claim perception IS reality. Thus if you
observe it, then it is.

Of course,

He could indeed calculate the timing in other so-called inertial
frames.

All inertial frames can be tranformed into all others by calculation.
What's your point? Is it that nature has an absolute sequencing and
perceptions cannot change this?
