But we keep putting humans in charge of writing software... > Keeping UTC within a second of UT1 has important real-world uses, including navigation and astronomy. So put the work of handling a rare, irregularly occurring event on the few who care rather than the rest of humanity? > redefining how we measure time to cope with bad code This is basically what leap seconds are, a redefinition of time to fit a messy reality. So again, why the assumption that we need a messy standard that all must fit to rather than a messy process of converting a simpler standard to solar ephemeris for the few who care?
