Frames timing

I am using x264 for a bit now and I have noticed that inside the stream the PTS
timings are not correct for B and P frames. 

When you take a closer look at the stream, you notice that the B-Frames and
P-Frames times are following each other in the PTS. But it shouldn't. In fact
the B-Frames times should be slightly before its' previous P-Frame time.

Also, the DTS are missing in every frames for a stream encoded by x264enc.
(Enclosed is a screenshot of the B and P-frames PTS times in a stream encoded
by x264enc v1.0.1.)

By the way the rule for a DTS is not exactly the same than for a PTS. Because B
and P frames timing are supposed to be following. 

Also, this problem result of a non smooth video when you try to run it on any
video player, because it's dropping b-frames with incorrect timing value.
However, when you deactivate the b-frames, it becomes smooth.

I tried to run x264enc version 0.10.19 and the PTS is correct, but the DTS was
still not present.

Regards.
