The AdjustTime method adjusts the internal performance time forward or backward. This is mostly used to compensate for drift when synchronizing to another source.
HRESULT AdjustTime( REFERENCE_TIME rtAmount );
Amount of time to add. This can be a value in the range from -10,000,000 to 10,000,000 (1 second to +1 second).
If the method succeeds, the return value is S_OK.
If it fails, the method can return E_INVALIDARG.
The adjusted time is used internally by DirectMusic. It is not reflected in the time retrieved by the IDirectMusicPerformance8::GetTime method.
