Cesium is used in atomic clocks, the most precise instrument of time-keeping. Atomic clocks keep very good time. The best of them lose no more than one second in a million years. Compounds Cesium compounds have relatively few commercial uses. Cesium bromide is used to make radiation dete...
Silica (SiO2) in sand and minerals in clay is used to make concrete and bricks. Silica, as sand, is also the main constituent of glass. Pure, crystalline silicon dioxide (quartz) resonates at a very precise frequency and is used in high-precision watches and clocks. Silicones are important...
Rubidium is the 23rdmostabundant elementin the Earth's crust. Rubidium chloride is used in biochemistry as a biomarker to track where potassium is taken up by living organisms. The hyper-fine electron structure of Rubidium-87 is used in some atomic clocks to maintain accuracy. The isotope Ru-...
Inside that BIF example, as you mentioned, they do not mention where the bitstream file (in your case system.bit) gets inserted. The bistream should be inserted between the FSBL image and the first user executable (in your case it is uboot.elf) so the Boot Image Format (BIF) l...
Aluminum metal is used in the container and packaging industry as aluminum foil (17%), in building and construction (18%), in electrical transmission (9%) and in transport, car, truck and aeroplane bodies, and engine blocks, (30%). Alloyed with quite minor amounts of Si, Cu, Mn Mg ...
atomic optical clockThe Stark shift due to blackbody radiation (BBR) is a key obstacle limiting the frequency uncertainty of optical lattice clocks. A well-characterized BBR environment is necessary to know exactly the temperature felt by the cold atoms. In our ytterbium clock, the lattice-trapped...
ATOMIC MASS 63.546 FAMILY Group 11 (IB) Transition metal PRONUNCIATION COP-per Copper and its compounds have many important uses in modern society. Most electrical equipment has copper wiring. Copper is also used to make many alloys. An alloy is made by melting and mixing two or mo...

It is also possible to use a timestamp from an NTP timeserver and start the clock with the ntp's timestamp, in order to have precise atomic time. An example of this can be found here: https://www.johnromanodorazio.com/ntptest.php. In the example the ntp timestamp is adjusted on ...
