No, it has not been mentioned.
Mark, I can point to three times it has been mentioned, in the last
month, in threads which you initiated.
1. https://lists.ffmpeg.org/pipermail/ffmpeg-user/2021-February/051961.html

You need TB aka timebase too.
TB is rational.
PTS is 64bit integer.

The Presentation Time Stamp (PTS) value which FFmpeg associates with
video frames and audio data is a 64-bit integer. There is an
associated time base attribute for each video or audio stream, which
gives the number of seconds between successive values of PTS. This
time base might be thought of as the resolution of PTS. Thus if you
have two PTS values pts1 and pts2, then the difference in seconds
between them is (pts2-pts1)*time_base. The time base can be
represented as a rational number, e.g. 1001/30000.…

As I told you back on 23. February, ffmpeg uses a timebase that is a
rational number, and is an attribute of the video stream, and can take
various values. The timebase could be 1/360000, or 1/24, or 1001/24000.
