*lol* You're not the first person to get all bunched up about that. The
problem with NTP is that it is a security hole. It's very easy for any
random person to spoof NTP packets and REALLY mess things up. The
precision needed for file-sharing over FTP only has to be down to the
second (~3 seconds if you do the long math) which an hourly rdate will
accomplish just fine, with only a trivial security risk. (and cuts down
on network traffic too).
