This came up in a Reddit thread[1] yesterday; anecdote from there[2]:

> "My favorite part is I have 3 Samsung Wifi Appliances including microwave and double oven and I really couldn’t think of a great feature other than the clock automatically setting. Well fuck me when I found out they don’t set themselves at all, and in fact they don’t even have memory so the slightest power outage means I have to reset $3k worth of appliances manually. Oh and each of them have different ways to set the clock so it’s always fun trying to set them differently in PM. No I’m not salty."

We've had clocks for decades that synchronize to atomic time sources accurate to within 1 second over 100 million years that automatically correct for daylight savings time that do it all by just listening to publicly available radio broadcasts, no wi-fi or information harvesting required.

This solution is so cheap that you can buy it in the cheapest alarm clocks.

This is not a good reason to have wifi on an oven.

In the US we have:

https://en.m.wikipedia.org/wiki/WWVB

> WWVB is a time signal radio station near Fort Collins, Colorado and is operated by the National Institute of Standards and Technology (NIST).[1] Most radio-controlled clocks in North America[2] use WWVB's transmissions to set the correct time.

Radio time has never worked for me in Boston on any of the devices I've owned. I'm sure I'm not alone. It's simply too far away or there's too much interference or both.

Atomic clocks are less reliable and require more expensive circuitry. Everyone has wifi and a simple SOC that has everything needed to run the oven, display, and do WIFI at the same time can be found for pennies. Plus, internet connected is a selling point.

Huh? Wifi soc is way more expensive than a statically tuned radio receiver. The atomic clock isn't in the device, that's the point.

I was thinking more of the case of poor reception where you need a receiver outside and the device is inside.

Ok, I did not know about that. Why isn't this more popular? I have a fancy $1000 high end microwave that does not have wifi and does not sync its time. We've learned to ignore its clock.

WiFi should provide a clock even if you're not connected.

Some routers (e.g. asus with asuswrt-merlin) can intercept all NTP traffics and redirect them to router's NTP server.

Can you elaborate, how does that work? Just having a wifi radio chip, you can get the time by listening to other wifi broadcasts in the area?

If only everything in my home would sync to my local NTP GPS time source...

or a notification on your phone when the oven is at temperature, has been left on, when the timer has gone off...
