If I list /proc/<pid>/fd I see a number of entries for sockets. These entries have timestamps. At first I thought they were when the socket was created. But it doesn't always appear to be the case.

What does this timestamp mean?

It looks like the entries in /proc/x/fd are instantiated the first time you access them (via a lstat(2) or any system call that has them involved), and that's where the time comes from.

Do you know where I can see the kernel source for this? – Dave Nov 20 '12 at 16:02
Somewhere in fs/proc/, probably fs/proc/base.c – Stephane Chazelas Nov 20 '12 at 18:06
