Post #15 Calibration clock

I use an atomic clock I picked up years ago when Sharper Image closed down their retail brick & mortar stores. It is more accurate than the Internet. There is a lag in transposing the information to wire from air reception of the radio time signal.

But as long as you consistently use the same source to set a watch....

Happy time keeping.

You have a cesium atomic clock?! I envy you. 1 second error in 1000 years!

No, that is the common term for atomic clock synced devices. Geez.

Sorry I didn’t know about the common term. There are actual atomic clocks on sale as you know.

I use one of these

(not really - use an Casio Waveceptor but couldn't miss the opportunity)

Kind of a dick comment. No, my mistake. That was a 100% total dick comment. Double Geez…

I use the Hodinkee app 😅 but I always set it 1 minute ahead to always have some buffer 👍 I think, thats the most swiss thing I ever said 🤣

NIST is what I use: https://time.gov/widget/widget.html

Free, accurate.

I remember when you could just synchronise your Windows PC with an atomic clock...

aaaand I just discovered that you still can 🥰 https://www.netzwelt.de/anleitung/168617-windows-10-so-synchronisiert-euch-atomuhr-2810.html (its german but you can translate it with google)

1 minute seems OK. I used to give a bit more margin on my watch before retirement. We used to call this minus 5 minutes-ism, Japanese punctuality 😉.

Cool clock. I've never seen that before.

I use the time.gov website like @Pallet_Fork .

Sunrise & a smartphone is good enough , I’m not co-ordinating a military op or a whip around the sun on an interstellar journey. Can I say it ? F&@k me

Helium clock the new quantum time keeping theory is like a second divided by 2.7 picosecond increment oscillations a second. About 1 sec out every billion years at a rough guess 😂 27 trillions of a second increments ! What ordinary person other than quantum computing model applications needs this accuracy?!?!

God tier post

Well, to answer my own question (sort of); turns out Junghans makes an app for iOS and Android that can set radio controlled clocks emulating any of the radio signals used around the world.

You still can.

Good, was not to be expected otherwise from Japanese people. In Switzerland, we also have the quarter-hour tollerance in academic circles. If you have studied, you can also be 15 minutes late. Its called "die Akademische Viertelstunde"

You schould post that under the post-apocalyptic-watch-post 🤣 take one with you during the apocalypse, you can always eat it

The Casio Waveceptor will pick up off regular radio waves like the ones broadcast out of Ft Collins CO, in North America. That’s fine unless the zombies take out NIST in Ft Collins. Even better might be a Seiko Astron, which sync time off the satelite atomic clocks aka GPS. Guessing those GPS satellites might be harder for the zombies to get to.

I use the ZuluTime iPhone app.

I use the Hodinkee app and sync the seconds hand to the 5 sec countdown chime. Works fine for me.

Man, talk about getting nasty, you just did it. You've just lowered the discussion. Sorry your skin is so thin you can't take any form of critical comment, and my comment is hardly critical at all.😜

If you go to Amazon and type in atomic clock, you get exactly the type of device I use; a quartz clock that is radio synced to the world time service which relies upon a cesium atomic clock for the time. A cesium atomic clock is a room full of equipment and I am not aware that the general public can purchase such devices, though Elon Musk probably could. Those devices are million dollars of equipment.

Otherwise you can by a "Conventional vapor cell atomic clocks are about the size of a deck of cards, consume about 10 W of electrical power and cost about $3,000. (WEB source)" Those are really accurate but are secondary in accuracy to the cesium clock.

Just to set the record straight.

I think your weird internet connected clock is neat.

Because I am a (reluctant) tax paying citizen, I utilize the time keeping service of the Naval Observatory in Fort Collins, CO. HTTPS://time.gov is my go-to for setting my watches.

Don't worry about it at all. Not worth any stress. I do appreciate your clarification and apology. It is all in good fun. 😀

That's a good one too. I use that when on the road.

Your post inspired this purchase. It's pretty neat to have a timepiece that you know is perfectly calibrated at all times. 👍

Thanks. 🤗
