Looks like the RR EHM system does three snapshots of engine performance, takeoff/climb/cruise, and then a summary report when the plane lands.
It will also make a report if a sensor detects a problem.
Presumably a summary report was found, indicating the plane completed the flight successfully and the time? That’s all I can think of that would indicate when the plane landed.
I presume it knows when the plane lands due to the weight on wheels sensors?
I guess it is also possible that a water landing might trigger the summary report.
I dunno...?

I find it a little unusual that any company, large or small, would allow 20 of its employees to travel on the same plane.
Wow.
It really sounds like the plane was hijacked. That either it landed on land in some distant location or it was taken to deep water to bury it.
WRONG!
Unnamed sources with unnamed ties to the ‘investigation’ do not a fact make.
Local news said
“The Wall Street Journal newspaper quoted U.S. investigators on Thursday as saying they suspected the plane remained in the air for about four hours after its last confirmed contact, citing data from the plane’s engines that are automatically transmitted to the ground as part of a routine maintenance program.
Hishammuddin said the government had contacted Boeing and Rolls Royce, the engine manufacturer, and both said the last engine data was received at 1:07 a.m., around 23 minutes before the plane lost contact.”
neither Boeing nor Rolls has said other wise. The ACARS is NOT a black box mime. It gives bursts of data from crucial flight times (take off, climb, descend, land). Other than that it is a monitor that would send IF a mechanical failure or error occurred that needed ground attention at landing.
the fact that the writer is UNAWARE of how ACARS operates is the first clue he has nothing
What if the plane landed in a long highway in a remote area and was refueled and took off again.
One of Clint Eastwood’s best movies was Fire Fox. Clint stole a top secret USSR plane and flew it to the Artic and then to an ally country.
He landed on the Artic ice and was refueled by one of our nuke submarines. Then, he took off again.
No need for a nuke sub on a remote road on a desert plain or in a jungle. You would only need a tanker truck with jet fuel.
