2:22:30? That’s an hour before the plane took off.

No, it's in Universal Coordinated Time, which was ten hours in advance of Hawaii Standard Time (HST). Greenwich Mean Time at the Prime Meridian was chosen as the world's time standard, and all air and marine traffic knows to work with that.

4:22:30pm HST would have been written 162230, but add 10 hours to the Prime Meridian and one gets 262230 hours, modulo 24, yielding 022230 on Dec. 12 (the next day). In that transcript, it got translated for humans "somewhat" as 2:22:30. Thanks for asking!
