# CVGetCurrentHostTime()

Returns the current system time.

## Declaration

```swift
func CVGetCurrentHostTime() -> UInt64
```

## Return Value

Return Value The current host time.

## Discussion

Discussion In macOS, the host time bases for Core Video and CoreAudio are identical—both are based on the mach_absolute_time function—so the values returned from either API can be used interchangeably.
