Timing: 4 fifteen moment quarters using a 15-moment halftime (while in the ArenaBowl, half-hour). The clock stops for out-of-bounds plays and incomplete passes only in the final 50 %-moment of regulation [seventy eight] and extra time and if the referee deems it needed for penalties, injuries or timeouts.
