SO_TIMESTAMPNS is undocumented

[alejandro-colomar]

Yesterday I had to timestamp messages received from a TCP socket. I found that there is SO_TIMESTAMP, but it uses struct timeval which AFAIK is obsolete.

Then I found in the web some pages that talk about SO_TIMESTAMPNS, but I couldn't find clear documentation about it, and there is absolutely nothing in the man pages.

So I had to try. I tried SO_TIEMSTAMPNS, and it does work, so I think it should be documented.

EDIT: I've found there is a 4-years old FIXME:

man-pages/man7/socket.7

Line 29 in a48d191

.\" SO_TIMESTAMPNS (2.6.22)
