Zusammenfassung: | Techniques are disclosed for performing time synchronization for a plurality of computing devices without relying upon a minimum measured delay. In one example, processing circuitry obtains time stamp data in accordance with an iteration of a synchronization operation for a timing protocol, wherein the time stamp data describes one or more measured delays for a path between a first computing device and a second computing device, computes a skewness estimate from the time stamp data using a regression analysis, the skewness estimate comprising a frequency difference between a first clock at the first computing device and a second clock at the second computing device, computes an offset estimate between the first clock and the second clock by applying a prediction model to the skewness estimate; and corrects at least one of the first clock or the second clock based at least on the offset estimate. |
