## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.5/script-reference/unityengine.md)

```csharp
public static double fixedTimeAsDouble { get; }
```

### Remarks

Fixed time is updated in regular intervals (equal to [Time.fixedDeltaTime](/engine/6000.5/script-reference/unityengine/time/fixeddeltatime.md)) until the [Time.timeAsDouble](/engine/6000.5/script-reference/unityengine/time/timeasdouble.md) property is reached. This property is the double precision version of [Time.fixedTime](/engine/6000.5/script-reference/unityengine/time/fixedtime.md) and offers more precision than a float or single value, particularly over extended periods of real-world time. In almost all cases, prefer [Time.fixedTimeAsDouble](/engine/6000.5/script-reference/unityengine/time/fixedtimeasdouble.md) over [Time.fixedTime](/engine/6000.5/script-reference/unityengine/time/fixedtime.md).
