肖洛霍夫摘要：Systems, methods and devices are provided to improve management and
accuracy of timestamps associated with sensor-based data. An indication is received of a
sensor event associated with data samples provided from a sensor having an output data rate. A respective timestamp is assigned to each of the data samples. Assigning the respective timestamp may include, responsive to a determination that the indicated event is an interrupt event, calculating an actual data sampling interval based at least in part on time intervals between previous sensor events and a on a quantity of the one or more data samples. Assigning the respective timestamp may alternatively include, responsive to a determination that the event type is a data flush event, assigning the respective timestamp based on an actual data sampling interval associated with one or more previous sensor events if the actual data sampling interval has been previously stored, and otherwise assigning the respective timestamp based at least in part on the output data rate. Correction logic and drift compensation may be applied to the assigned respective timestamps.
