This seems to be to most common (and verifiable via ADS-B) reported departure and ditching times. Five hours, fifty-four minutes.

The aircraft had departed Santa Rosa-Sonoma County Airport, California (STS) at 15:21 UTC (08:21 local time) on a flight to Honolulu International Airport, Hawaii (HNL).
ADS-B data suggests that the aircraft at some point turned back, heading for HAF, until it crashed at 14:15 local time.
