For North America folks interested in low-maintenance, accurate atomic/radio clocks, but live outside the expected WWVB range¹ :

The La Crosse UltrAtomic large wall clock has a semi-novel internal two-antenna design that allows the WWVB signal to be picked up at greater distances (such as southcentral Alaska) when conditions are favorable (especially at night).

And since the modern WWVB signal² embeds DST/ leap seconds / etc well in advance of actual changes, and since the oscillator is relatively low drift ... the time accuracy window is pretty robust.

It takes either two or four D batteries. Four will get you around four years of life in ANC (in my experience).

So between the self-setting and the long battery life .... you can put a visible, affordable, low-maintenance clock in a hard-to-reach place, even in Alaska.

And here's a great teardown for the geeks:

#WWVB #Alaska #TimeNut

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

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.
