This is always a person-by-person opinion. Some people don't want copies
(because they assume that others know that they always read the list in a
timely matter), some want copies (to make sure they read it), some want
comments that tell them that it is also copied ... Since I now know your
preference, I'll try to remember.

I may have been looking at different code. If I recall correctly it only
used gettimeofday() if it was using the old behaviour (as mentioned in the
manual page).
I was looking at iputils_20001110.orig.tar.gz as downloaded from debian's
site. The manual page contains "iputils-ss990107".

As mentioned in another email by Fernando, his ping does have that
feature. I guess you are using a different ping. (And my ping doesn't have
that feature either.)
-U Print true user-to-user latency (the old behaviour).
I don't use that ping. I have came across well over 20 messages about this
problem. Some of these messages indicated the upgrading to a newer kernel,
or using "-U", or using an older ping fixed their problem.
Feel free to ask the developer pekkas @ netcore.fi what he means by
"SIOCGSTAMP/SO_TIMESTAMP are sensitive to bug in kernel" and if this
applies to this.
