Remarks
This property returns a value of type LONGLONG, representing the current physical time in 100-nanosecond units.
The physical time of a clock is an ever-progressing counter. Unlike the presentation time, it cannot reverse.
Clocks are not required to support a 100-nanosecond resolution. To determine the clock resolution, clients can use the KSPROPERTY_CLOCK_RESOLUTION request.
