# CMTimebaseSetAnchorTime(_:timebaseTime:immediateSourceTime:)

Sets the time of a timebase at a particular host time.

## Declaration

```swift
func CMTimebaseSetAnchorTime(_ timebase: CMTimebase, timebaseTime: CMTime, immediateSourceTime: CMTime) -> OSStatus
```

## Discussion

Discussion The system interpolates CMTimebaseGetTime’s results from the anchor time. CMTimebaseSetTime(timebase, time) is equivalent to calling CMTimebaseSetAnchorTime(timebase, time, CMSyncGetTime(CMTimebaseCopySource(timebase))).
