Scott LairdHuh. Now that I have <a href="https://hachyderm.io/tags/otel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#otel</a> traces on a bunch of things at home, it's pretty clear that my clocks aren't in sync on every system. They're maybe 1ms off, but it's enough that supposedly-nested trace spans aren't quite nested right.Which is annoying since I have two local GPS <a href="https://hachyderm.io/tags/NTP" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NTP</a> receivers.The two "bad" machines were using <a href="https://hachyderm.io/tags/systemd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#systemd</a>-timesyncd to talk to Ubuntu's pool clocks instead of the local clocks. The "good" machines are using <a href="https://hachyderm.io/tags/chrony" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chrony</a> and claim that they're ~2 us off of GPS time.Now I'm curious -- is this a problem with network latency and Ubuntu's pool, or is that just as good as timesyncd gets?

adminForge :cloud:NTP – Zeitserver Ein neuer adminForge Service kann ab sofort genutzt werden.Eine geographische Nähe zu einem Zeitserver ist wichtig um die höchstmögliche Genauigkeit der Zeitsynchronisation zu bekommen. Du kannst jeden unserer Server in deiner NTP-Konfiguration verwenden.

Stefans WeblogOpenWRT – Verschlüsselte Zeitsynchronisation mit chrony chrony is an implementation of the NTP (Network Time Protocol). It has some advantages against the standard ntpd (= Network Time Protocol daemon).chrony can synchronize to the timeserver much faster than NTP. This is good for laptops or desktops that don't run constantly.<a href="https://strobelstefan.de/blog/2023/08/31/openwrt-verschluesselte-zeitsynchronisation-mit-chrony/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://strobelstefan.de/blog/2023/08/31/openwrt-verschluesselte-zeitsynchronisation-mit-chrony/</a><a href="https://mastodon.social/tags/chrony" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#chrony</a> <a href="https://mastodon.social/tags/NTP" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NTP</a> <a href="https://mastodon.social/tags/OpenWRT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenWRT</a> <a href="https://mastodon.social/tags/Time" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Time</a> <a href="https://mastodon.social/tags/TimeSynchronization" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TimeSynchronization</a> <a href="https://mastodon.social/tags/Timeserver" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Timeserver</a>
