Yep. CPU scheduler runs on Central time, and gets confused if your departure is on different days in (1) local time at the departure airport, and (2) Central time. Canonical example is redeye flights from Hawaii, but anywhere in Pacific/Mountain time can produce it if your departure is after midnight Central.
