public class FrameTimings

A FrameTimings object holds timing information for a single frame of the application’s displays.

To retrieve FrameTimings objects, use get_timings or get_current_timings. The information in FrameTimings is useful for precise synchronization of video with the event or audio streams, and for measuring quality metrics for the application’s display, such as latency and jitter.
