How do I get the actual DNG shooting time?

We are using DNG burst shooting mode with https://www.dji.com/zenmuse-x7 to SSD.
However,  all the files timestamp in the directory are identical, so we don’t know the actual shooting time.

According to the flight log (CAMERA_INFO.isStoring), it seems that 9:21.166 video recording time, generated 10067 frames.
I.e. An average of 17.939 fps
However, according to the spec, it should be 20 fps.


This rais the question if we get the DNG’s in constant rate? (Or best effort, pending on buffer transfer rate etc.)

Thanks for clarifications.
