Thanks for the pointer, nice project. However, one side-note: the y-axis label in the diagram shown on the google code page can't be correct - the unit must be ms, NOT µs. An offset smaller than +-200ns is imho ways out of reach for such devices, 200µs is feasible. In particular when considering the mechanisms used according to the PpsGpioPollDriver description (100µs interval waiting/polling). Still the accuracy is good and should be sufficient for many tasks.
