That's quite correct. That's why you can't account for this
effect as being due to acceleration.

SR doesn't do that. SR predicts that the elapsed time
on a clock displaced by (dt,dx) is ds = sqrt((dt)^2 - (dx/c)^2).

Integrate ds along the two world lines and you will see the difference.
And ds is Lorentz invariant so that all observers agree about the
outcome of the experiment.
