What's a 2×4 ultra clock?
In this video, the uploaders describe a mechanism to "automate" the mining of trees by filling blocks around and above tree you mine with air, while accelerating the speed at which "random ticks happen". At 0:59, the video mentions that the contraption is powered by a "2×4 ultra clock."
What's a so-called "2×4 ultra clock"? The weird thing is that the actual enclosed by the command blocks quite clearly is 2×2×1...
Best Answer
They meant 2x2.
What they call "Ultra clock" is also known as a fill clock: one command block does a /fill command with redstone blocks, another one does one with a different kind of block (e.g. stone). The rest of the command blocks will now get activated 20 times per second (each game tick).
The /fill command is currently only available in the snapshots.

What is the difference between quartz clock and atomic clock?
Atomic clocks are actually quartz clocks\u2014just like the ones you have at home. The difference is that an ordinary quartz clock relies purely on the oscillations of its quartz crystal to count seconds.Which is the most accurate atomic clock?
Today, the most precise clocks are based on a natural atomic resonance of the cesium atom\u2014the atomic equivalent of a pendulum. For example, NIST-F1, one of the world's most accurate time standards based on microwave atomic clocks, neither gains nor loses a second in 20 million years.What is an atomic clock used for?
Today, the exquisitely precise timekeeping of atomic clocks is used for measuring time and distance for everything from our Global Positioning System (GPS), online communications across the world, fractions of a second in trading stocks, and timed races in the Olympics.Do atomic clocks still work?
The radio controlled clocks (atomic clocks) sold in North America are permanently tuned to receive and synchronize with the National Institute of Standards and Technology atomic clock radio station WWVB in Boulder, Colorado.what. (Bo Burnham FULL SHOW HD)
