Agree. In other words, computers should use UT1 (where one day is a rotation of the earth, and 86400 seconds; and consequently a second is not a SI second).

- acqq 8y agoCorrect, time_t second is already in practice not an "SI second" the later being defined by the "counts" in the "atomic" clocks: "the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom" (at a temperature of 0 K)" https://en.wikipedia.org/wiki/Second https://en.wikipedia.org/wiki/Second That SI second is what I refer to when I mention an "atomic clock second." The time_t second is effectively simply one 86400th of a day.
