ntp.conf vs. step-tickers

I've got two suites. Both suites have servers with a ntp.conf and step-tickers file. Both suites are running fine with respect to time. One suite of servers has empty step-ticker files, the other one has content in the files.

Do I need both files? Should the files be populated? Should the two file types agree? I need a quick tutorial of the two file types and how they work together. Or, please point me to a web site with the information I need.

My thanks to whoever can assist.

You should have a step-tickers file in all servers that are running ntpd. This is the file that is used by ntpd to call ntpdate and set the correct time when the daemon starts up.

What happens? The startup script in /etc/rc.d/init.d/ntpd will read the servers in the step-tickers file and execute the ntpdate command as follows:

Code:
 /usr/sbin/ntpdate -s -b -p 8 your.time.server.in.step.tickers

For example, if the time of the hardware clock is way off, it is possible that ntpd will not start.
