Temporality

After spending an action you imprint yourself at that moment in time onto the back drop of reality. For the duration of the spell you function as normal. When the spell ends you can teleport back to where the spell was cast, exactly as you were when you cast it. All gains and loses are reversed, but you retain all memories of the events that transpired. It still costs a spell slot to use.

If your concentration is broken your connection to that moment is lost and the spell fails. You can choose to drop concentration at any time without triggering the effect of the spell.

At 4th and 5th levels the duration of the spell increases to 15 minutes and then 1 hour.
