Can The Logs Be Trusted If they Can't Keep The Correct Time?

    Everyday many decisions are made solely on the data recorded & logged by the drones, both on the UAV and DJI Go app. If this cannot keep correct time (i.e. time clock runs fast gaining 1 minute every 6 actual minutes) can we trust any of the data? Or is it keeping correct time as it is programmed and DJI just wants to say flight times are longer than they are?

    Anyone else experience this?

    It's most likely a playback speed issue, the number displayed on the screen would be correct but the flight replays too quickly at times, you see it's not consistent on your video. Most likely the app just plays the number of telemetry reports it's supposed to receive per second, but when some are missing because they were lost during transmission it results in a speedup.

    But to answer your question no, I wouldn't rely on that log for anything but "curiosity". If you're required to keep logs by all means don't use those and write things down yourself separately.
