The REFERENCE_TIME data type is a 64-bit integer. Reference times are usually measured from one of the following baselines: * An absolute clock time. In this case, the baseline will depend on the implementation of the clock. For more information, see Reference Clocks. * Relative to the start of playback. For more information about reference times, see the Microsoft documentation on Time and Clocks in Media Foundation or DirectShow.
