The Time Turner, unknown to you and hours prior to any spinning, creates a near-duplicate of you (and itself) somewhere in the world
The Time Turner contrives for you to end up end up exactly like the duplicate it created, n hours later, and then compels you to turn itself (like ComedTea compels you to drink it).
On being turned, the TIme Turner destroys you and itself.
