WebA PTP algorithm that filters packet delay variation (PDV) converges more slowly than a PTP algorithm that does not. By default, the BC uses a linear feedback controller (that is, a servo) to set the BC's time output to the next clock. The linear servo provides a small amount of PDV filtering and converges in an average amount of time.
