Were they using computers that had time-of-day clocks? None of the computers that I've owned gave time-of-day.
The Sherwood Wisdom also gives the dive date and the time-of-day the dive began and ended.
This exact time info would help to figure out if there were other divers in the water when/after the incident occurred, but I guess it wouldn't necessarily be reliable because the clocks may not have been synchronized or correct.
