- offset
- TimeSpan
대상 클록의 시간으로 측정된 검색 오프셋입니다. 이 오프셋은 origin의 값에 따라 클록의 BeginTime 또는 Duration을 기준으로 합니다.
- origin
- TimeSeekOrigin
지정된 오프셋이 대상 클록의 BeginTime 또는 Duration을 기준으로 하는지 여부를 나타내는 값입니다.

설명
Seek 작업 적용 되지 않습니다는 SpeedRatio 또는 SlipBehavior 계정에이 clock의 타임이 라인의 설정을: 시계는 해당 타임 라인에 처럼 처리 됩니다는 SpeedRatio 1 및 no SlipBehavior합니다.
SeekAlignedToLastTick clock 이며 마지막 클록 틱의 seeked에 맞춥니다. 값으로 인해 변경 내용을 반영 하도록 즉시 업데이트 됩니다 SeekAlignedToLastTick이지만 화면 화면 업데이트 될 때까지 이러한 변경 내용은 반영 되지 것입니다.
대상 클록에 자식이 해당 현재 그에 따라 업데이트 됩니다.
이 메서드가 변경 시계의 CurrentState 에 Active입니다.
