A pair of programs for keeping computer clocks accurate. chronyd is a
background (daemon) program and chronyc is a command-line interface to it.
Time reference sources for chronyd can be RFC1305 NTP servers, human (via
keyboard and chronyc), and the computer's real-time clock at boot time (Linux
only). chronyd can determine the rate at which the computer gains or loses
time and compensate for it whilst no external reference is present.
chronyd's use of NTP servers can be switched on and off (through chronyc) to
support computers with dial-up/intermittent access to the Internet. chronyd
can also act as an RFC1305-compatible NTP server.
