preferred way to use DeviceTimeSync

The changes are working for me with an accuracy of about ~20msec, so I close the issue, thanks!

Hello

I have a solution that implements the algorithm you describe, but integrated without extra callbacks. I'll merge this in.

The L2 spec (1.0.4) doesn't actually say when the server should record a timestamp. Looks like it should be the time at TX complete (from device perspective) but I only find this out by looking at TTN and ChirpStack.

edit:

To answer your question LDL @ version 0.5.3 would pass the time to the application at RX1 or RX2 without any compensation. This is as you found out no good for time sync.

The changes are now in master.

I'm yet to try it on real hardware.

Thanks for the update, I'll test it in a few days.
