The values shown in this pic can be found in the raw data from FR24, and the corresponding time stamp is 04:13:17.761, or about four seconds after the upset, which appears at 04:13:13.671.
Given this was an official FR24 receiver, the time
should be GPS synched. I don't know anything about the clocks in the FDR and CVR.
