SPTP does look a lot like NTP over PTP. I’m guessing they deployed this last year when nothing like it existed - the ietf draft (dated Jan 24, 2024) came much later after. They might even be involved with it. Anyways, it’s nice to see progress towards a simpler protocol that retains the precision of PTP.

How does SPTP compare to CERN's WhiteRabbit, which is built on PTP? https://en.wikipedia.org/wiki/White_Rabbit_Project

FWIW, from "50 years later, is two-phase locking the best we can do?" https://news.ycombinator.com/item?id=37712506 :

> TIL there's a regular heartbeat in the quantum foam; there's a regular monotonic heartbeat in the quantum Rydberg wave packet interference; and that should be useful for distributed applications with and without vector clocks and an initial time synchronization service

It's older than that, but not sure how much older.
