## Definition

```csharp

```

### Remarks

This value is equal to [Time.deltaTime](/engine/6000.3/script-reference/unityengine/time/deltatime.md) when it is constant (i.e. smooth frame rate). When deltaTime varies between frames (e.g. on a frame hitch), this value increases or decreases gradually towards deltaTime over multiple frames.

See [Time and Frame Rate Management](/engine/6000.3/manual/scripting/object-oriented-development/managing-time-and-frame-rate.md) in the User Manual for more information about how this property relates to the other Time properties.
