The number is bafflingly small. The largest possible value this fundamental unit of time could be is one thousandth of a quectosecond, according to research published last month in the journal Physical Review Letters. That’s ten to the -33rd power or, as Live Science helpfully put it, just one millionth of a billionth of a billionth of a billionth of a second. And that’s just the upper limit, based on the performance of the best atomic clocks we have. In the abstract world of mathematical theory, Live Science reports the absolute smallest unit of time could be yet another 100 billion times shorter.

Can it represent quectoseconds though? I need my time to be really precise and nanosecond just doesn't do the trick.

Within SI there is the zeptosecond: 1 zs = 0.001 as = 10⁻²¹ s, and the yoctosecond: 1 ys = 0.001 zs = 10⁻²⁴ s. The CIPM has prepared draft resolutions submitted to and to be voted on by the CGPM in 2022–11, one of which involves four additional scaling prefixes to SI, two of which are relevant to the question. These prefixes will not be official unless and until approved by the CGPM, so there is a small risk that I am jumping the gun: the rontosecond: 1 rs = 0.001 ys = 10⁻²⁷ s; the quectosecond: 1 qs = 0.001 rs = 10⁻³⁰ s.
