Browse around in other refclock drivers looking for sample code. It will probably be something like pp->fugdgetime2, but that assumes somebody has setup pp correctly. I don't think you are going to have much luck introducing a "drift" to the ATOM driver. It expects the PPS signals on second marks. That's time, not frequency. drift applies to frequency rather than time. Pleae let us know if it works. -- These are my opinions, not necessarily my employer's.
