Scott Laird's personal blog at scottstuff.net covers systems and hardware. Since 2023, 11 different Hacker News readers have linked it 11 times, most often “Timing Conclusions: GPS, NTP, PTP Timing with Linux”. It is still writing: the last post was on 2026-10-31, and you can follow it by feed.
Too few sampled comments (4) to say how often HN recommends it.?
Why HN links it
HN readers link Scott Laird's blog for a multi-part series on NTP and PTP timing accuracy on Linux, including a concluding post, and a post on using an 8K TV as a Mac monitor.
Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

In case you're wondering whether this works on a Mac, like I did, I found this source[0]. In short, you need an M2 Pro or better, and may need to edit a plist file to get it to work. [0] https://scottstuff.net/posts/2023/10/10/samsung-8k/

HN discussionI agree with most of what you said. The author has other posts in the series where he tried to measure the accuracy relative to the PHC (not system clock) using PPS: https://scottstuff.net/posts/2025/06/02/measuring-ntp-accura... Steering the same PHC with phc2sys as chronyd is using for HW timestamping is not the best approach as that creates a feedback loop (instability). It would be better to leave the PHC runnin…
