ACARS timestamps
Does anyone know if the timestamps shown on the list are transmitted (e.g. originated in the aircraft) or added at the receiver? It might make a whole difference to the timeing of the events.
Generally fault lists are time-stamped at the originator. However, in a low bandwith situation like transmission of data on a HF-link, time and date might not be transmitted as they are not crucial for maintenance purposes. Then, serialized and delayed, the string of events in the list might be stretched or even out of order of occurence.
