rclockd is a unix daemon which will systematically update the system time with the time received from a radio clock attached to the serial port.

Depends only on pthreads and the date command. Manpages and usage instructions are included in the tarball.

Installation should just be a matter of:

          ./configure
          make
          make install
        

An example rc init script is built in the scripts/ folder. It is compatible with redhat based systems and supports chkconfig. Just copy to /etc/init.d and run chkconfig --add rclockd to set up the boot script on redhat based systems.
