Timestamp of socket in /proc/<pid>/fd

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.
