The CMSensorRecorder returns a CMSensorDataList of CMRecordedAccelerometerData objects.

CMRecordedAccelerometerData is a subclass of CMLogItem which has a timestamp property.  The timestamp should be "the amount of time in seconds since the device booted".

The time stamp is incorrect and is always offset by a constant amount from the expected time stamp.
