Whether the underlying timestamp data for the sensor could be provided in the public APIs. And a question about the unit of accelerometer data.

For example, AccelerometerData has only one property which is a Vector3 . The gyroscope and magnetometer is the same. So I don‘t know how to get the accurate time the sensor acquires the current data. Is it possible to add a property of timestamp data in the struct?

I've tried to use DateTime.Now when ReadingChanged event is invoked, just like: (based on the document)

private void Accelerometer_ReadingChanged(object sender, AccelerometerChangedEventArgs e)
{
    // Update UI Label with accelerometer state
    AccelLabel.TextColor = Colors.Green;
    AccelLabel.Text = $"Accel: {e.Reading}";
    AccelTime = DateTime.Now;
}

But it seems to be kind of weird since it is not the real time when the data changes. There is a period of time between when the accelerometer actually gets the data and when the event responds. And why the unit of accelerometer is G(9.81 m/s^2)? As a university student studying navigation engineering, I need to use the timestamp of sensor data in many inertial navigation algorithms, where the accelerometer data is in m/s^2. And that means I need to multiply by 9.81 manually after I get the data to convert the unit from G to m/s^2. I think it makes no sense to set the unit of accelerometer data to G, since gravity varies around the world.
