[time-nuts] Do GPS augmentation services improve 1pps?

[Azelio Boriani]

When the PPS is generated by the internal free running oscillator,
there is nothing to do: the sawtooth correction must be considered.
The augmentation service will provide a better sawtooth estimate and a
better position estimate as well.
