Steps to reproduce the problem:
I'm not sure if I can reproduce this in a public example. I can try if it's needed.

What is the expected behavior?
The timings should be consistent

What went wrong?
On the attached screenshots, the 1st one is from network tab (613ms), and the 2nd one is from timeline tab (3s). And I can tell that the timeline tab got it right, at least as far as the UI is concerned.

Did this work before? N/A 

Chrome version: 52.0.2743.116  Channel: stable
OS Version: OS X 10.11.6
Flash Version: Shockwave Flash 22.0 r0

Maybe it's not a bug, just an UX issue. I find it hard to understand why should the timings be so different.
