What is "hypertime"

n. Any of various fictional or theoretical time-like constructs that extend beyond normal time, usually by encompassing or spanning many distinct timelines (sometimes infinitely many).

Hypertime is a fictional concept presented in the 1999 DC comic book series The Kingdom, both a catch-all explanation for any continuity discrepancies in DC Universe stories and a variation or superset of the Multiverse that existed before Crisis on Infinite Earths.
