Keep civil time monotonic and with a consistent number of seconds per day by not even trying to keep the UTC rate constant or the second boundaries synchronized with TAI, just follow the Earth's rotation. Earth is a clock of limited precision, but will at least remain a monotonic clock as long as it remains habitable (i.e, if we get whacked by some planet-sized impactor hard enough to make Earth rotate backwards, our primary concern will be a planet-wide game of "the floor is lava"). >
