Maybe someone can educate me (and Steve you've done a good job at this
in the past), but I see the "I've restricted even the servers I
specified from telling me what time it is" question come up regularly
in these discussions. Is there some website, or some old set of man
pages, or some popular book, or something out there that causes this
same question to occur over and over and over again?
