If you're not willing to have a privileged reference frame, how do time turners know where to go?

(Especially thorny is that the surface of the earth accelerates upwards relative to inertial reference frames; if you stay in your inertial reference frame played backwards through time, you don't lose the earth in space, but you do oscillate through it like a mass on a spring. I personally think this is a really cool way for time travel to work, but it's clearly not how time turners do).
