I don't "believe" it. I *know* that a "day" is the length of time it takes
the little hand of the clock to rotate completely twice. Or, more
precisely, the specific clock at NPL.

Actually, as we've discussed here ad nauseam, where I live the "day" is
de jure the mean solar day at Greenwich and de facto 794243384928000 periods
of the radiation corresponding to the transition between the two hyperfine
levels of the ground state of the cesium 133 atom.
