+chrony is a pair of programs which are used to maintain the accuracy of the
+system clock on a computer; the two programs are called chronyd and chronyc.
+
+chronyd is a daemon which runs in background on the system.  It obtains
+measurements via the network of the system clock's offset relative to time
+servers on other systems and adjusts the system time accordingly.  For
+isolated systems, the user can periodically enter the correct time by hand
+(using chronyc).  In either case, chronyd determines the rate at which the
+computer gains or loses time, and compensates for this.  chronyd implements
+the NTP protocol and can act as either a client or a server.
+
+chronyc provides a user interface to chronyd for monitoring its performance
+and configuring various settings.  It can do so while running on the same
+computer as the chronyd instance it is controlling or a different computer.

+Unfortunately, this software has shameful history of several vulnerabilities

+come to an end.  It is further complicated, as chronyd(8) requires superuser
+permissions to operate; please type ``make deinstall'' to deinstall the port
+if tight security is a concern.
