Yes. These features are under development and should be available soon…
But not in recent days since I'll be unable to program in nearly a week.
It depends on how late it is.
If it's a latency that is at most 500 ms, it is the app's bug. Poweramp's API only enables apps to count time in seconds, so… (the reasons are shown after permissions are granted properly). However, there is a plan to make the segments more detailed, for about 100 ms, but this is not a promised feature, since in current stage performance and power consumption are not evaluated yet.
If the latency is more than 500 ms, try pause and resume(double-click the play button) in Poweramp. That possibly fixes it, which resets the time Poweramp passes to 3rd party apps.
