French Decimal Time & .beats (法國十進制時間)

FRENCH REVOLUTIONARY DECIMAL TIME — the Republic's boldest reform after the calendar itself: by the decree of 4 Frimaire An II (24 November 1793), the day was TEN HOURS, the hour a hundred decimal minutes, the minute a hundred decimal seconds — 100,000 seconds to the day, NOON AT FIVE. Clockmakers built dual-faced watches; almost nobody used them; mandatory force lasted seventeen months (suspended 7 April 1795) — the reform that proved you can decimalize everything except the day people already live: the metre and kilogram conquered the world, the decimal hour died in the clock shops of Paris. THE ARITHMETIC AS LAWS: one decimal second = 0.864 s, one decimal minute = 86.4 s, one decimal hour = 2 h 24 m, five-o'clock noon, and the full-day conversion BIJECTION proven at load. THE RESURRECTION LAW is the smile: Swatch's 1998 '.beat Internet Time' — 1,000 beats, no time zones, Biel Mean Time — is EXACTLY the French decimal minute count (10 × 100 = 1,000; one beat = 86.4 s, asserted, with the @000/@500 BMT anchors): Switzerland reinvented Revolutionary France's minute two centuries later and called it the future. Western becomes forty-nine. Pure compute, no LLM.
