# USDLayer.TimeOffset

A time transformation applied when composing layers.

```
struct TimeOffset
```

## Overview

Consists of an offset (time shift) and a scale factor. Used in
references and payloads to remap animation timing from a referenced
layer into the referencing layer’s timeline.

## Topics

### Initializers

[`init(offset: Double, scale: Double)`](/documentation/USDKit/USDLayer/TimeOffset/init(offset:scale:))

Creates a time offset with the given shift and scale.

### Instance Properties

[`var isIdentity: Bool`](/documentation/USDKit/USDLayer/TimeOffset/isIdentity)

Whether this offset has no effect (`offset == 0`, `scale == 1`).

[`var isValid: Bool`](/documentation/USDKit/USDLayer/TimeOffset/isValid)

Whether both `offset` and `scale` are finite (not NaN or infinite).

[`var offset: Double`](/documentation/USDKit/USDLayer/TimeOffset/offset)

The time shift applied during composition.

[`var scale: Double`](/documentation/USDKit/USDLayer/TimeOffset/scale)

The scale factor applied during composition.
