 ## Timing
 
+Several functions to synchronize clients using the synced time you can retrieve using `api.getTime()`.
+
 ### toTimeSpan
 
+Creates a timespan object.
+
+```javascript
+api.GameLib.Timing.toTimeSpan(duration, startTimestamp?);
+```
+
+| Argument                  | Type   | Description                                          |

+| (Optional) startTimestamp | number | The start timestamp of the timespan in milliseconds. |
+
+**Return** [TimeSpan](./ModuleApiGameLibTimeSpan) _TimeSpan instance._
+
 ### toFrameCycle
 
+Creates a frame cycle object.
+
+```javascript
+api.GameLib.Timing.toFrameCycle(startTimestamp, frameInterval, totalFrames, startFrame?);
+```
+
+| Argument       | Type   | Description                                             |
