Title: Using chrony as a replacement fot ntpd
Post by: lilsense on June 13, 2018, 12:56:06 am
Would it be possible to include https://chrony.tuxfamily.org/  (https://chrony.tuxfamily.org/)either as an add-on or default NTP server/client.

Here's an excerpt from the site's FAQ:

chronyd was designed to work well in a wide range of conditions and it can usually synchronise the system clock faster and with better time accuracy. It doesn’t implement some of the less useful NTP modes like broadcast client or multicast server/client.

If your computer is connected to the Internet only for few minutes at a time, the network connection is often congested, you turn your computer off or suspend it frequently, the clock is not very stable (e.g. there are rapid changes in the temperature or it’s a virtual machine), or you want to use NTP on an isolated network with no hardware reference clocks in sight, chrony will probably work much better for you.

For a more detailed comparison of features and performance, see the comparison page on the chrony website.

I use chrony on all my Debian machines, it's basically like having an Atomic Clock. If a Firewall/Router were running it you could still have other instances such as chrony in all my machines configured to sync with the Firewall/Router's chrony. Like NTP, it is suggested to not load down the servers out there with many instances from one network versus just having your Firewall/Router query and all your machines inside your network querying the Firewall/Router. Not sure how much this really matters these days though.

It's possible, NTP can already be disabled globally (remove all servers).

What we need is packages, maybe also for openntpd?

And then a contributor for a plugin....
