By default, `FieldValue.serverTimestamp()` values that have not yet been set to their final value will be returned as `null`. You can override this by passing an options object. Signature: ```typescript /** @override */ data(options?: SnapshotOptions): T; ``` ## Parameters | Parameter | Type | Description | | --- | --- | --- | | options | [SnapshotOptions](./firestore_.snapshotoptions.md) | An options object to configure how data is retrieved from the snapshot (for example the desired behavior for server timestamps that have not yet been set to their final value). | Returns: T An `Object` containing all fields in the document.
