구현 주석

Accepted date inputs: an instant, never a wall-clock string.

Strings are deliberately absent. new Date('2026-06-08T09:05:00') resolves an offset-less string against the device zone, so the same API payload becomes a different instant on different phones — and no timeZone option can undo that, because it happened before the formatter saw the value. Parse strings with {@link parseIsoInstant}, which makes that choice explicit.

A number is epoch milliseconds.
