# from

Fetches sample information that occurs after this time.

## Declaration

```swift
var from: SRAbsoluteTime { get set }
```

## Discussion

Discussion A fetch is exclusive of this time. The framework requires the app to define a value for this property. If an app fails to define this property, the framework responds to the fetch by providing SRError.Code.fetchRequestInvalid to the reader delegate via sensorReader(_:fetching:failedWithError:).
