I guess that's possible, though I might think it unlikely anyone who
understands the distinction would assume a function called `real-time'
in fact gives wall time.

Or one could assume that since -run-time is unaffected then -real-time
is also unaffected.

If the system time doesn't change too often then I guess there's not
much difference.  But I can't help thinking that it's not good for a
function called real-time to go backwards or suddenly jump forwards.
