 This chapter includes network service packages.
 
+- Time
+
+  Everyone should be setting their system clock from a reliable source. The
+best sources for time are the Global Positioning System (GPS), or a
+stand-alone atomic clock. GPS is the usually more practical than stand-alone
+options. There is a large community of reliable time servers on the Internet,
+all of whom eventually source their time from GPS receivers connected to
+almost two dozen satellites circling the globe (which have atomic clocks
+onboard). Reliable time is required by many other services, such as Bind9 and
+Kerberos.
+
+  The Network Time Protocol (RFC 958) sets the guidelines for Internet based
+time servers. Several software packages are available conforming to this
+protocol for almost all operating systems.
+
+  The most popular time software for Linux is NTPD (http://ntp.isc.org/). NTPD
+includes support for several protocols, including NTPv1 (RFC 1059),
+NTPv2 (RFC 1119), NTPv3 and NTPv4 with control messages support (RFC 1305),
+and Time Protocol (RFC 868). NTPD also includes sophisticated algorithms used
+to calculate false tickers, and clock discipline. If you are looking for full
+featured time keeping then this is the software for you. To install NTPD
+simply follow the BLFS instructions:
+http://www.linuxfromscratch.org/blfs/view/svn/basicnet/ntp.html
+
+  Rdate is a time utility for Linux (http://freshmeat.net/projects/rdate/).
+Rdate is used for one time query and setting of time from a remote system
+using the Time Protocol (RFC 868). NTPD's 'ntpd -q' preforms almost the same
+function as this software. To install Rdate simply follow the rdate.txt page
+in this chapter.
+
+  Another NTP daemon available for Linux is OpenNTPD (http://www.openntpd.org/).
+OpenNTPD is minimalistic and only conforms to NTPv3 without control messages
+support (RFC 1305). It features privilege separation and strict programing
+style but lacks many of the features found in NTPD. OpenNTPD is not intended
+to be a complete replacement for NTPD. OpenNTPD includes the minimum set of
+features that the majority of users will need. To install OpenNTPD simply
+follow the instructions in openntpd.txt in this chapter.
