If the observer brings his own co-moving copy of the Solar System he
will notice that the rotation time of his own copy of Earth won't match
the rotation time of the original Earth.

Same. He will notice that the length of a meridian won't change on his
own copy of Earth while it will be shorter on the original Earth.

Case closed: SR is consistent.
