    In the tlog time_boot_ms will go down.  So if it was 1821515 and you reboot it might now be 12058.  It should never go backwards and only ever increase.

    Thanks, Grant.

      can I see it as well in the LOG from the SD card?

      for example the attached flight with crash - I suspect an issue with the power system leading to a reboot of the Pixhawk (which was all the time in manual mode) - even though a zener diode and capacitor were installed.

      Thanks a lot, Felix

        For a dataflash log (.BIN) you use TimeMS which is logged against all entries.  So I did a simple mavgraph (you can do the equivalent in MissionPlanner) like this

        mavgraph.py --flightmode apm CTUN.TimeMS 88.BIN

        and it produced the straight line like this

        3702720568?profile=originaland as you can see it never went backwards so there was no restart in flight.

        Thanks, Grant.

          sorry - one more question,

          can I see from the LOG file if the safety button was pressed (i.e. the vehicle disarmed or armed)?

          thank you very much, Felix
