Even more accurate clocks using optical lattice.

Analog power supply?


(I have to be careful poking fun at this one -- I have a Nixie clock)

me too, mine loses a minute every six months, probably a couple of centuries in billion years (no I didn't do the math)

1142 centuries.

Depends on mean altitude (or gravity), so no aberration for Netherlands

I'm at 60 ft (18 m) not helping my clock much

World’s Most Accurate and Precise Atomic Clock Pushes New Frontiers in Physics

The clock is the latest demonstration that a much more precise definition of the official second is possible and that new applications of clocks are feasible.

Pretty impressive. Accurate to within 1 second per 30 billion years. Moving it far less than a millimeter causes the rate of time to change due to a change in the curving of space by gravity.

I bet it will just flash "12:00:00" for 30 billion years and then "11:59:59" for the next.

Did you allow for leap years?
ahem

Kid... I like your style.

The physics hasn’t been invented that satisfies a true audiophile…

Yes! The unshakable faith in snake oil is profound! Thst said, as a thing, this click precision is amazing! BTW, I feel compelled to throw some shade on the respondent who claims to hear side bands to -300dB. That is a power ratio of 1 X e-30. I don’t believe for a minute the respondent can hear that small degree of jitter!

I did round it off in centuries so leap years falls in between the cracks. Maybe I should have used galactic revolutions or as it is known the galactic year (roughly 225 million earth years), but I didn't know of the leap value for that one. Plus I suspect the value hasn't been stable since the big bang. We are currently in galactic year 61 since the big bang.

I like your style as well.

Glad I didn't just Google it, with all this Kumbaya

I recall some of the guys in my lab working on a Rhodium-based chip-scale atomic clock. It didn't pan out though.

He is parodying audiophiles - at least one of whom claims to be able to hear -300dB. A manufacturer trying to justify his expensive DAC designs using ludicrous numbers of filter taps.
