@MarkHenderson Ugh, really? People, SAs, really ever do that? I've *always* used an exernal, trustworthy ntp source. Guess I'm just super-talented and just didn't know it.
Hell, even the monstrously bad environments I've found myself in managed to at least do that right, pointing something (in some cases, too many somethings) at an external, public ntp server.
