Meta-time
From Jenny Everywhere Wiki
Meta-time was the measure of time being incrementally rewritten. Going backwards in meta-time would mean going back to an old, now-overwritten version of reality. As such, it was exceedingly difficult. However, Sophie Everytime managed it at an early age to find out Jenny Nowhere's original name, admittedly with the help of her Cousin Tiny.
