My original posting: I am writing to ask if someone can explain the
use of the NTP_TIME kernel option, and to ask if someone can explain
what NTP encryption is and why one would want to use it.
====================
SUMMARY of responses
====================
If you want to use ntpd, you need kernel support for it. The
encryption is used for communication between time hosts (MD5).
See
http://www.eecis.udel.edu/~ntp more beautiful pages
This is a very standard time keeping protocol. It works best when you
have an Internet connection. It points to the official time keepers on
the Internet and synchronizes with them - works great. All of this
managed by the National Institute of Standards - you can find all the
info at www.nist.gov
use the ntpsetup script. on a TruCluster ASE150 failover, run the
ntpsetup master on one machine and the client on 2nd machine. Then on
second machine set ntpsetup master and the client on the other
machine. Now both clocks are set to the same time. If one drifts in
time the server from the other will correct the time to match each
other.

you may want to have a look at the NTP home page at
http://www.eecis.udel.edu/~ntp/ . You should find a description of the
precision time kernel there as well as a description of NTP encryption.
