NTP Precision Limitations
Discussions focus on the limitations of NTP in terms of precision, security, and reliability for high-accuracy needs, with frequent mentions of alternatives like PTP, chrony, and GPS-based syncing.

NTP isn't enough, you need PTP.
About time, given NTP's debatable (in)security history.
Ah, I've never had a use case for anything more accurate than NTP
I wonder if any of the other ntp implementations (chrony et al) suffer from this same issue?
Should've used NTP or PTP.
SNTP is close to useless. Your time server could be off and you'd happily follow along.
You aint running ntp if you need nanosecond precision and accuracy.
Why not just use NTP to get time data from someone else’s (more accurate) atomic clock?
Best case NTP is in the order of millisecond precision. Completely inadequate for this case.
Why the complexity of NTP (network & internet) when you could use a GPS syncing wall clock for much less?
