I have all machines sync every 15 minutes via cron to the local "stratum 
0" time server by running "ntpdate" . There are several ways 
to do it in Slackware, and it all revolves around one's level of 
paranoia as to how to do it. With the server pools, one has to worry 
about external open ports and system profiling, which is why I picked 
the "internal" server for mine. Where to stick that pesky gps unit was 
my only worry lol.
