# locTimestampUs

URL: https://www.caprid.com/docs/reference/typescript/caprid/moq-media/functions/loctimestampus/

```ts
function locTimestampUs(properties, options?): number | undefined;
```

Defined in: [loc.ts:95](https://github.com/caprids/relay-sdks/blob/main/ts/packages/moq-media/src/loc.ts#L95)

An object's LOC Timestamp in microseconds, or `undefined` when it has none. Scales by the first usable Timescale on
the object, then in the track properties, rounding ties upward. With none, the Timestamp is
already microseconds: LOC's wall-clock time since the Unix epoch.

## Parameters

| `options?` | [`LocTimestampOptions`](https://www.caprid.com/docs/reference/typescript/caprid/moq-media/interfaces/loctimestampoptions/) |

## Returns

`number` \| `undefined`
