I feel that what we have covered here will stand you in good stead for setting up your NTP network. We have looked at many aspects of time, everything from the scientific definition of time (how long is a second?), all the way through to setting up NTP servers using various NTP relationships in order to try to provide a calibrated and accurate time to our system. If you want some further reading, there is a great document supplied with HP-UX that covers most of what we have talked about. The document lives in:
root@hpeos002[] # ll /usr/share/doc/NTP_Primer.txt -r--r--r-- 1 bin bin 50413 Apr 24 2001 /usr/share/doc/NTP_Primer.txt root@hpeos002[] #
The only other thing to remember is to keep timeservers running for as long as possible. They will calibrate their clocks more accurately over time and be more able to serve your public well.
