%description
The oscillatord daemon takes input from a PHC clock, reporting once per second,
the phase error between an oscillator and a reference GNSS receiver. For an
example of such a device, please see the ptp_ocp kernel driver.

The phase error read is then used as an input to the disciplining-minipod
library which will compute a setpoint, used by oscillatord to control an
oscillator and discipline it to the 1PPS from a GNSS receiver. Oscillatord also
sets PHC'stime at start up, using Output from a GNSS receiver.

To communicate with GNSS receiver's serial it uses ubloxcfg
