/**
 * A date/time value stored as an Elasticsearch/OpenSearch `date`.
 *
 * - **ES/OpenSearch mapping:** `{ type: 'date' }`, optionally with a `format`.
 *   The `config.format` is only carried through to ES when it is a custom
 *   (non-`DateFormat`) pattern or an epoch format; `DateFormat.seconds` is
 *   normalized to `epoch` and `DateFormat.milliseconds` to `epoch_millis`,
 *   since ES only understands `epoch`/`epoch_millis`. When no usable format
 *   is present the `format` key is dropped (via `withoutNil`). Honors
 *   `indexed: false` (emitted as `index: false`).
 * - **GraphQL:** `String` (ISO-8601 date strings).
 * - **xLucene:** `Date`.
 *
 * @example
 * const config: DataTypeConfig = {
 *     version: 1,
 *     fields: { created: { type: 'Date' } }
 * };
