Most recent spec is IEEE 1588-2019.
- aidenn0 7y agoNTP is more than good enough to get 7ms synchronization on a LAN when working correctly, so the fact that PTP can do even better is perhaps uninteresting in light of the fact that NTP often fails to get anywhere near its theoretical performance (other comments mention clocks off by years).
