How to get timestamp from tlog format?

Posted by scaple on August 12, 2013 at 9:39am

Andrew has told me that the tlog format is very simple - an 8 byte microsecond timestamp followed by the raw MAVLink packet.
I have parsed Mavlink packets from tlog file, but I can't get timestamp. What is the varible type for this timestamp? uint64_t or double? and how to get hour, minute and second from it?

Thanks.

    Hi,

    Try to download (git clone really) the source code for Mission Planner. There you will find it (eventually).

    It is some 8 byte type for a timestamp, correct. For some reason I don't know, as far as I remember the 8 bytes are reversed in order. So try re-reversing and see if that helps.

    Regards

    Soren
