Clients use the KSPROPERTY_CLOCK_TIME property to determine the current presentation time on a clock.
Usage Summary Table
| Get | Set | Target | Property Descriptor Type | Property Value Type |
|---|---|---|---|---|
| Yes | No | Pin | KSPROPERTY | LONGLONG |
Remarks
This property returns a value of type LONGLONG, specifying the current presentation time in 100-nanosecond units.
The presentation time of a clock can be reversed, unlike the physical time. The presentation time of a clock typically represents a timestamp on an underlying data stream. For example, a clock for a DVD player can report the timestamp of the current position in the DVD as its presentation time.
Clocks are not required to support a 100-nanosecond resolution. To determine the clock resolution, clients can use the KSPROPERTY_CLOCK_RESOLUTION request.
