How does Cuckoo time accuracy compare?
This diagram shows actual time requests from Cuckoo and several major NTP servers on the Internet. The data collected for this chart comes from our YellowBill application. Several important facts can be gleaned from this chart. • PC Clock Drift – Over the course of the test run (about one day), this PC’s clock drifted about 800 milliseconds, or almost one second. This is represented by the upward sloping line from left to right–the further the distance from 0, the further the PC’s clock is from true time. This is pretty typical performance of most new commercial PCs. Older or off-brand machines can often be much worse. • Latency – Notice that all of the Internet servers (not Cuckoo) have periods where their time readings are significantly skewed. This primarily comes from Internet routing latency. The NTP protocol is designed to correct for this by slowly slewing your computer’s clock to match the average time. But the more discrepencies, the longer this process can take. • Repeatabil
