Further details are on the <a href="manyopt.html">Automatic Server Discovery</a> page.</p> <p>Once the NTP software distribution has been compiled and installed and the configuration file constructed, the next step is to verify correct operation and fix any bugs that may result. Usually, the command line that starts the daemon is included in the system startup file, so it is executed only at system boot time; however, the daemon can be stopped and restarted from root at any time. Once started, the daemon will begin sending and receiving messages, as specified in the configuration file.</p> <h4 id="time">Setting the Time and Frequency</h4> <p>The <tt>ntpd</tt> program operates by exchanging messages with one or more servers at designated intervals ranging from about one minute to about 17 minutes. When started, the program requires several exchanges while the algorithms accumulate and groom the data before setting the clock. The initial delay to set the clock can be reduced using options on the <a href="confopt.html">Server Options</a> page.</p> - <p>Most compters today incorporate a time-of-year (TOY) chip to maintain the time during periods when the power is off.
