Live Science: Physicists create groundbreaking atomic clock that’s off by less than 1 second every 100 million years…
Scientists have developed one of the most precise atomic clocks ever built, and they plan to use it as a reference clock to define time itself... #atomicclock #time #physics
Atomic Clock trades Receiver for an ESP8266.
Well, you’d still have a clock. But you’d have to set it manually like some kind of Neanderthal. That wasn’t acceptable to [jim11662418], so after he yanked the misbehaving WWVB receiver from his clock, he decided to replace it with an ESP8266 that could connect to the Internet and get the current time via [NTP].

This modification was made all the easier by the fact that the WWVB receiver was its own PCB, connected to the clock’s main board by three wires: one for the clock signal, another that gets pulled low when the clock wants to turn on the receiver [usually these clocks only update themselves once a day], and of course, ground. It was simply a matter of connecting the ESP8266 dev board up to the two digital lines and writing some code that would mimic the responses from the original receiver.](https://files.mastodon.social/cache/media_attachments/files/114/444/213/855/219/011/original/66c77a8c09a56f75.png)

If you take a look through the provided source code, a comment explains that the WWVB signal is recreated based on the official documentation from the National Institute of Standards and Technology (NIST) website.

There are functions in the code to bang out the 500 ms “one” and 200 ms “zero” bits, and once the microcontroller has picked up the correct time from the Internet, they’re called in quick succession to build the appropriate time signal. As such, this code should work on any clock that has an external WWVB receiver like this, but as always, your mileage may vary.
This is a very clean hack, but if you wanted to pull off something similar without having to gut all the clocks in your house.](https://files.mastodon.social/cache/media_attachments/files/114/444/213/879/314/761/original/ecd2d44f1f1c2158.jpeg)
🙄🎉 Oh wow, another atomic clock to tell us we're late for our meetings! Because what the world needed was a timepiece with a fancier name... 🚀⏰ Bravo, #NIST, for giving us the luxury of being precisely late on #government time.

What if a nuclear clock could measure time 100x more precisely than today's atomic clocks? JILA’s latest discovery could change everything. #QuantumPhysics #AtomicClock #DarkMatter
Ah, yes, because clearly the answer to GPS hacking is... more clocks! 🕰️✨ Let's just slap an atomic clock on every plane and hope hackers are too busy setting their alarms to notice. 🚀⌚ Genius!

Plane GPS systems are under sustained attack - is the solution a new atomic clock?
As a Ryanair flight from London approached Vilnius, Lithuania, on 17 January, its descent was suddenly aborted. Just minutes from touching down, the aircraft's essential GPS suffered an unexplained interference, triggering an emergency diversion.
How a new atomic clock might be the way to tackle attacks on plane GPS systems.

Every morning, I check my #NWS #WeatherRadio and my #NIST #AtomicClock signal, y'know, just to make sure they're still funded. 😨

Chip scale #AtomicClock|s cost a small fortune, but they’re the size of a matchbox and make it all possible. It’s amazing how small atomic clocks can be. (nei) #CSAC

Well, that was cool - it got the #AtomicClock signal from over 2,000 KM away and just changed over to the correct time all by itself. Now I will never have to do that again. #SYS64738

Good morning, friends. ⏰🕰️☕

Oh gee, I looked at my bedside clock when I awoke this morning, saw that is was seven AM, and jumped out of bed like I was late for something. I usually get up around six or earlier. I'd forgotten about the end of daylight savings time and I have one of those atomic clocks that automatically, gets the time from a time server somewhere. Whenever I mention atomic clocks, I visualize that they have a tiny nuclear reactor inside 😂. They just have that name; they really receive the time information from a real atomic clock that measures time from the frequency of atoms. Anyway, I guess seven O'clock is the new six O'clock, or is it the other way around.
