Choosing beginning and end timestamp

[Mtbarros]

Not sure if this feature would be useful to most people, but since I flew an IC engine, I left my pixhawk armed for a very long time before the flight (~40mins). Would it be possible to choose a general start and end timestamp for the logging data?

I've read other issues which mention sincronizing between graphs would be too hard, but would it be too hard to implement this, just simulating that the log started later or ended earlier for all data?

Thank you for your time.

From a UI/UX perspective it is not something that is simple to do (and also make it easy to use).
I suggest you create a new log for an actual flight, as then your log files will also be smaller.
But if someone wants to implement that I can help out.

@bkueng is it possible to track takeoff & landing times?

[bkueng]

Yes but this is not necessarily reliable.
