Well, present NTP drops to a nonroot user after it sets the time &
proprer use of the very flexable ACL lists in your ntp.conf should help
midigate
non-local NTP exploits, ie, don't offer NTP service to the world or anyone
else
for that matter.

I need better than one second resolution for syslog and other loging info to
be useful
in debugging problems across multiple hosts.
