+ system service that may be used to synchronize the
+ local system clock with a remote Network Time Protocol
+ server. It also saves the local time to disk every
+ time the clock has been synchronized and uses this to
+ possibly advance the system realtime clock on
+ subsequent reboots to ensure it
+ monotonically advances even if the system lacks a
+ battery-buffered RTC chip.</para>
