WebThe Precision Time Protocol, PTP, is designed to synchronize clocks on a local area network (LAN) to sub-microsecond precision. The underlying assumption is that the accurate time source is on the same LAN as the systems that are synchronizing their clocks. That differs from NTP, which assumes that the time server is remote. WebAug 17, 2024 · If you want a higher precision at the cost of more wasted CPU cycles, you can change this to: return estimate = mean + X * stddev and then replace X with any constant you like.
