@cstross@wandering.shop But minutes are terrible to work with; the Babylonian obsession with base 60 is outdated. Can we go with accumulated seconds since some benchmark in a specific frame of reference? 100 seconds to the metric minute -- bonus: "I'll be with you in a minute" now 25% more likely to be correctish. 1 kilosecond is the time it takes to do anything non-trivial, so it is a reasonable unit for estimating how long something should take. 30 kiloseconds is a working day or a good night's sleep. Those are all the timescales that people need to deal with shorter than a day, and everyone reaches for a calculator if they need to turn minutes or hours into days anyway. Keep the seconds, redefine the minutes and drop the hours, that's my take.
