Most TSD machines stopped support of the netdate command because it fails to
do simple bounds checking. Which, yeah, is pretty bad, but easy to fix -- I
emailed that author of that page a few weeks back asking if they'd
reconsider opening access to port 13 if a new version of netdate came out
that actually looked at its input before attempting to set the time.
Actually, a few of their machines are still open but I didn't mention this
because it's a handy way to set the time.
