THE LEAP SECOND
precise about the wrong quantity
1 WHAT IT IS · WHAT IT DOES · FACT OR FICTION
Unix time counts seconds since 1970. It does not. It counts days since 1970, multiplied by 86,400 — and the Earth has had twenty-seven extra seconds inserted into it that the count refuses to hold.
LIT verified live. between 1 January 1972 and 1 January 2017 there are 16,437 days. Unix time makes that 1,420,156,800 seconds — exactly 86,400 per day, with no remainder. Actual elapsed time is 1,420,156,827 seconds, because 27 leap seconds were inserted in that window, the first on 1972-06-30 and the last on 2016-12-31. So a Unix timestamp is not an elapsed-second count and never was; the difference is 27 seconds, all of them positive, and 0 negative leap seconds have ever been needed.

2 HOW IT WAS WEAVED · AI + HUMAN
Leap seconds are declared by the IERS to keep UTC within 0.9 s of the Earth’s rotation; the twenty-seven dates are theirs and are used here as data, not re-derived.
AVAN (AI) reports the divisibility as the finding: 1,420,156,800 mod 86,400 = 0. That is not a coincidence and it is not a rounding — it is the definition. Unix time is a calendar rendered as a number, and the smooth axis everyone assumes it is has twenty-seven places where two different instants share one value, or one instant is skipped, depending on the implementation.

The green forward object.
AVAN’s addition (the inverse-companion): the forward reading is that Unix time is a convenient approximation. The inverse is that it was never approximating elapsed time — it is exactly right about a different quantity. The count is days-times-86,400, and as a statement about the calendar it has no error at all. Read backwards, the bug is not in the clock but in what everyone decided it measured; a number that is precisely correct about the wrong quantity is far harder to notice than one that is merely imprecise.
