Jared0425:
I doubt SOSUS would ever release the recordings. Too much information can be gathered about its positioning.

The video in question isn't purporting to be SOSUS recordings, but the text transmissions between Titan and Polar Prince. Besides the timestamp issue, it describes the sub descending at a fast rate (if anything, Titan's test dives showed it to be fairly buoyant due to the carbon fiber hull), reporting an alarm from the acoustic monitoring system on the hull, and trying to surface for 15 minutes prior to the loss of comms. While we do have thirdhand reports that the sub was attempting to surface when contact was lost, if those details were correct I would think they would have been corroborated by other accounts and they would raise questions about the search activities.

Is there any reason a vessel would not use nearest local time or local time at point of departure, or is that "spotting the thread?"

Yes, but I see no reason for a civilian vessel to do that.
 
Hek, all my diving is recorded in the log as GMT (well in the computer.... I don't actually log) ... If I was a boat, that's all I would ever use.
 
I wouldn't be surprised if that transcript is accurate. I believe there's another obvious fake out there that has audio of screaming, which is probably the sensationalistic route someone would go to fake a transcript. Nothing about the dry, back-and-forth typing transcript seems fake. The timestamp being off by one time zone is meaningless; maybe they're all just set to East coast time.

Snopes has moved it to false from unconfirmed and provides plenty of information to justify the move.

For the curious: Was the Titan Sub's Text Message 'Transcript' or 'Log' Released?

Efficiency and brevity were a priority. There was absolutely no chitchat (such as "Enjoy the dive, gentlemen"). Often, the actual exchanges even omitted the verb, newspaper headline-style ("Bottom time up"), to save time and typing.

If everything were indeed fine, the pilot would simply text "AN" (the code for "All systems nominal"). Nobody would bother to type out "Systems check complete, all in order. All lights are green." Or this absurd example: "All systems are functioning normally. We're in good shape. Continuing our descent as planned." That's complete baloney.

Imagine that you're texting a friend. Would you ever actually type out "Affirmative"?! Not unless you were a hoaxer trying to sound rockety. No, you'd just type "OK."

...

Pogue said of these three messages, "As I've reported, Titan had seven different ways to return to the surface: hydraulically released construction pipes, a set of rolling construction pipes (released by rocking the sub), sandbags (mechanically released), an air bladder, the thrusters, the timed self-releasing sandbags (connected to the sub with seawater-dissolving links), and, FINALLY, the frame (legs) of the submersible."

"The Titan's pilot would not just say 'Going to release the ballast now'; he would specify which kind," Pogue added. "And above all, he would never not BEGIN with the expensive, custom-built frame! He would BEGIN with the pipes, sandbags, thrusters, or air bladder."

That’s true about using abbreviations. When providing a SITREP during a mission we had to say who, what, where and when. So for example if we were on our way back to the base we would say hey you this is me grid 12345678, RTB with 4 Vic’s and. 20 pax, RTB time now. Translation : hey this me, we are at grid 12345678, we are returning to the base right now with 4 vehicles and 20 men.
