 ### gizmos
 
 **Arguments**
 
 * `callback: function`. A function that receives two parameters:
-    * `time: DOMHighResTimeStamp`. Elapsed time, in milliseconds, since an arbitrary reference. This parameter is kept to mimic web standards, but its usage is discouraged. Prefer using `frame.session.time.elapsed` and `frame.session.time.delta` instead. These are especially useful for creating animations. See also: [Time](time.md).
+    * `time: DOMHighResTimeStamp`. Elapsed time, in milliseconds, since an arbitrary reference. This parameter is kept to mimic web standards, but its usage is discouraged. Prefer using `frame.session.time.elapsed` and `frame.session.time.delta` instead. These are especially useful for creating animations. See also: [TimeManager](time-manager.md).
     * `frame: Frame`. A [Frame](frame.md) holding the data you need to create the augmented scene.
