var from: SRAbsoluteTime { get set }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:).
