Lately I've been looking at my graphs more often because I switched the NTP implementation on my server from to . Overall, I'm quite impressed with chrony - although it seems to be so good I wonder if I'm plotting comparable data. :)

Last week, I did a major OS upgrade and replaced a dumb switch with a managed one and set up LACP. Doing this however seems to result in weird latency/time offset spikes. Unplugging one of the two members cleans it up.

Clock synchronization without gone wrong:

> Microsoft introduced the time-keeping feature in 2016 as a way to ensure that system clocks were accurate [...] Sometimes, the clock times jumped by a matter of weeks. Other times, the times changed to as late as the year 2159

Any folks out there with the latest best practices around ? I'm working on a network that locked down access to external NTP servers heavily back when amplification attacks were becoming common. We have an internal NTP server with restricted outbound access, but I'd like for critical infrastructure like domain controllers to be able to fall back to external servers if the internal one goes down. Any "gotchas?"

@tails For example, I do want to preconfigure some basics like @torproject and settings like "use Port 890 & 443 only" which allows me to do, but doesn't.

Or at least they don't allow me to just change a config file on the to do so.

Worse: I can't even do a single via without having a connection up and running, which is really bricking stuff.

Trying to find a presentation about ntp I came across on Masto some time ago. It was following the chain of time providers from ntp back to standards bodies and historic definitions of time by repeatedly asking the question: “… and where does x get the time from?”

@flamesoulis I saw a piece from the people about an server with an external antenna. Sorry my memory isn't better, but I think it used a co-ax between antenna and . Maybe their magazine.

Why the timesyncd client does not receive any reply from the NTP server (time out in reply)?

Good news everyone! There's not going to be a leap second inserted in the UTC time scale at the end of December 2023.

(given the overall trend in the rotation of the Earth, this shouldn't be a surprise...)

I’ve only done a quick search on this but am not finding what I want. Assume I’m making a with and . For this clock, I’d like it to display the current time but with an offset of 10 or 15 minutes. (Sometimes people like to set their clock ahead to help them stay on schedule.) The clock does network time sync with or so that its internal system time remains accurate. Is there a way to configure the time display offset?
