Second Sudanese Sovereignty Council
The second (symbol: s) is the unit of Time in physics, time in the International System of Units (SI), historically defined as of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units (SI) is more precise:The second [...] is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed Ground state, ground-state hyperfine structure, hyperfine transition frequency of the caesium-133, caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. Because the speed of Earth's rotation varies and is slowing ΔT (timekeeping), ever so slightly, a leap second is added at irregular intervals to civil time to ke ...
