 		<h4 id="descr">Description</h4>
 		<p>The <tt>ntpd</tt> program is an operating system daemon that synchronises the system clock with remote NTP&nbsp;time servers or local reference clocks. It is a complete implementation of the Network Time Protocol (NTP) version 4, but also retains compatibility with version 3, as defined by RFC-1305, and version 1 and 2, as defined by RFC-1059 and RFC-1119, respectively. The program can operate in any of several modes, as described on the <a href="assoc.html">Association Management</a> page, and with both symmetric key and public key cryptography, as described on the <a href="manyopt.html">Authentication Options</a> page.</p>
 		<p>The <tt>ntpd</tt> program ordinarily requires a configuration file as described on the Configuration Commands and Options collection above. However a client can discover remote servers and configure them automatically. This makes it possible to deploy a fleet of workstations without specifying configuration details specific to the local environment. Further details are on the <a href="manyopt.html">Automatic Server Discovery</a> page.</p>
