# offset

The time, in seconds, at which the animations begin within the duration.

## Declaration

```swift
var offset: TimeInterval { get set }
```

## Discussion

Discussion The default value is 0, which indicates that the animation plays with no offset. Setting a value for this property moves the animation data along the timeline and doesn’t change timing. If you set a fillMode other than none, the animation fills the vacant area created by the offset according to the characteristics of the specified fill mode.
