Abstract
Accurate correction of a local clock that avoids excessive drift in the local clock while avoiding an accumulation of quantization errors. A local clock according to the present techniques generates a local time by accumulating a sequence of rate coefficients selected from a plurality of rate coefficients using a series of progressively longer replacement periods.
