Abstract
Technologies for low-power and high-accuracy timestamps are disclosed. A compute device may have a sensor hub to capture sensor data with a corresponding timestamp. In order to save power, the sensor hub may be able to capture sensor data while the compute device is in a standby mode. However, the always running timer of the compute device may not be accessible to the sensor hub while the compute device is in the standby mode. The sensor hub may have a coarse-grained counter and/or fine-grained counter. To correct for any temporal drift, the compute device may determine an error between the always running timer and the coarse-grained and/or fine-grained counters when the compute device is out of the standby mode, and store an indication of the error in a location accessible by the sensor hub, even when the compute device is in the standby mode.
