140 Nanosecond Worst Case NTP Performance with TimeKeeper
TimeKeeper® routinely produces sub-microsecond accuracy from NTP sources. In the graph below, a TimeKeeper client tracks an NTP source to within 140 nanoseconds. The client is setup with four sources: two independent GPS sources for validation (blue and green), a PTP source (yellow), and an NTP source (orange). The worst case (not average) NTP source accuracy is within…
