«Ubuntu setzt auf ntpd-rs — Rust für präzise Zeitsynchronisierung:
Ubuntu plant, ntpd-rs als Standard für die Zeitsynchronisierung einzuführen. Die Rust-Implementierung soll chrony und weitere Tools ersetzen.»
Ich bin kein @ubuntu Fanboy aber ich mag @rust und deswegen sehe ich deren Einsatz sehr positiv.

Secure time synchronization with NTS
To set the correct time on computers, usually NTP (Network Time Protocol) is used. However NTP is an insecure time synchronization protocol and allows a man-in-the-middle to shift time on an NTP client. To tackle these issues, NTS (Network Time Security) was created which aims to solve these problems. In this article I show how you can configure ntpd-rs and Chrony to use NTS servers. systemd's timesyncd does not support yet NTS, but it's currently in development so hopefully this will be […]https://blog.frehi.be/2026/03/29/secure-time-synchronization-with-nts/
NTP in practice. Mostly it works. Time to time it's like 8 hours off. Internet connection is working.
I already debugged unreliable NTP once and replaced the unreliable "ntp" NTP daemon with much more reliable "chrony" NTP daemon. But still unreliable.
"Old people don't like computers" - because computers are unreliable! Why would I use something that's unreliable? A tuning fork ground out of quartz, invented by Seiko, connected to a battery, semiconductor amplifier, 15-bit counter, few logic gates, stepper motor, cogwheels, hands and a clock face is much more reliable!

GPS-gestützter Zeitserver mit Raspberry Pi: So baust Du Deine eigene Grandmaster Clock
Mit einem Raspberry Pi und einem GPS-Empfänger lässt sich ein präziser Stratum-1 Zeitserver aufbauen – inklusive PPS-Signal und PTP-Unterstützung. So entsteht eine kostengünstige Alternative zu teuren Grandmaster Clocks, die exakte Zeit im ganzen Netzwerk be

Just like DNS way, way, waaaaaaaay too many seem to mess up NTP. So I wrote a thing about monitoring NTP with OpenSearch/ElasticSearch.

there is a wide gap in the understanding of NTP (and PTP) amongst many IT Organizations. Most appear to be ignorant of RFC8633 containing Best Current Practice (BCP), including recommendations for the stable, accurate, and secure operation of NTP infrastructure.
