Nothing is recorded 'continuously' on a DFDR. All parameters, including time, are sampled by the FDAU at specific intervals, with a certain accuracy and a certain resolution, and sent to the DFDR to be recorded. The DFDR does not generate a 'time' parameter as such. I don't know if the 'very accurate elapsed time-base' resides in the FDAU or in the DFDR, but it only serves to write subframes at intervals of very accurately one second.
Where are the seconds ?
In the Frame Counter, (range 0 to 4095, sampled 1 per subframe of 1 second and labelled TGEN in the printout).
