/** * Split a UTC interval at arbitrary `points`, producing consecutive sub-intervals. * * - `points` need not be sorted — they are sorted internally before splitting. * - Points outside `[start, end]` are dropped; they cannot introduce a boundary that isn't * inside the interval. * - Points exactly on `start` or `end` are dropped too — they would only produce a * zero-length sub-interval at the edge. * - Duplicate points collapse to a single boundary. * - Returns `[{ start, end }]` (the whole interval, unsplit) when no valid in-range point remains. * - Returns `[]` when `points` is not an array, when any element is not a valid ISO UTC * datetime string, or on invalid input (unparseable start/end, `start > end`, leap-second * strings). * * @param start ISO UTC datetime string for the interval start * @param end ISO UTC datetime string for the interval end * @param points array of ISO UTC datetime strings to split at * @returns array of `{ start, end }` records, or `[]` on invalid input * * @example intervalSplitAtUtc("2024-01-01T00:00:00Z", "2024-01-10T00:00:00Z", ["2024-01-05T00:00:00Z"]) // [{ start: "2024-01-01T00:00:00Z", end: "2024-01-05T00:00:00Z" }, { start: "2024-01-05T00:00:00Z", end: "2024-01-10T00:00:00Z" }] * @example intervalSplitAtUtc("2024-01-01T00:00:00Z", "2024-01-10T00:00:00Z", []) // [{ start: "2024-01-01T00:00:00Z", end: "2024-01-10T00:00:00Z" }] * @example intervalSplitAtUtc("invalid", "2024-01-10T00:00:00Z", ["2024-01-05T00:00:00Z"]) // [] */ export declare function intervalSplitAtUtc(start: string, end: string, points: string[]): Array<{ start: string; end: string; }>;
