Abstract
A computer system is arranged with a circular buffer that includes a piecewise linear map from a high-resolution counter arranged to maintain International Atomic Time. The piecewise linear map includes a current leg that is currently being used and also a future leg that will be used in the future. The future leg is computed while the current leg is still being used.
