CBaseReferenceClock.SetTimeDelta method

The SetTimeDelta method adjusts the internal clock time.

Syntax

HRESULT SetTimeDelta(
  [ref] const REFERENCE_TIME &TimeDelta
);

Parameters

TimeDelta [ref]

Amount to adjust the clock time, in 100-nanosecond units. A positive value moves the clock forward, and a negative value moves the clock backward.

Return value

Returns S_OK.

Remarks

The derived class can use this method to adjust the internal clock, if it drifts from the device that is providing timing information.

The CBaseReferenceClock::GetTime method never returns decreasing values. If you adjust the clock backward, GetTime returns the previous value until the clock reaches that value again.

Requirements
