+# ModuleClientApi - GameLib
+
+Class representing the GameLib inside the ModuleServerAPI.
+
+## 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                                          |
+| ------------------------- | ------ | ---------------------------------------------------- |
+| duration                  | number | The duration of the timespan in milliseconds.        |
+| (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                                             |
+| -------------- | ------ | ------------------------------------------------------- |
+| startTimestamp | number | The start timestamp of the frame cycle in milliseconds. |
+| frameInterval  | number | The interval between frames in milliseconds.            |
+| totalFrames    | number | The total number of frames in the cycle.                |
+| startFrame     | number | The start frame of the cycle.                           |
+
+**Return** [FrameCycle](./ModuleApiGameLibFrameCycle) _FrameCycle instance._
+
+### toRatio
+
+Creates a ratio object.
+
+```javascript
+api.GameLib.Timing.toRatio(value);
+```
+
+| Argument | Type   | Description             |
+| -------- | ------ | ----------------------- |
+| value    | number | The value of the ratio. |
+
+**Return** [Ratio](./ModuleApiGameLibRatio) _Ratio instance._
+
+### getCurrentFrameIndex
+
+Gets the current frame index of the frame cycle.
+
+```javascript
+api.GameLib.Timing.getCurrentFrameIndex(cycle);
+```
+
+| Argument | Type                                       | Description         |
+| -------- | ------------------------------------------ | ------------------- |
+| cycle    | [FrameCycle](./ModuleApiGameLibFrameCycle) | FrameCycle instance |
+
+**Return** number _The current frame index._
+
+### getFrameIndexAtTimestamp
+
+Gets the current frame index of the frame cycle.
+
+```javascript
+api.GameLib.Timing.getFrameIndexAtTimestamp(cycle, timestamp);
+```
+
+| Argument  | Type                                       | Description                              |
+| --------- | ------------------------------------------ | ---------------------------------------- |
+| cycle     | [FrameCycle](./ModuleApiGameLibFrameCycle) | FrameCycle instance                      |
+| timestamp | number                                     | The timestamp to get the frame index at. |
+
+**Return** number _The frame index at the given timestamp._
+
+### getCurrentTimeSpanRatio
+
+Gets the ratio of the current time span.
+
+```javascript
+api.GameLib.Timing.getCurrentTimeSpanRatio(span);
+```
+
+| Argument | Type                                   | Description       |
+| -------- | -------------------------------------- | ----------------- |
+| span     | [TimeSpan](./ModuleApiGameLibTimeSpan) | TimeSpan instance |
+
+**Return** [Ratio](./ModuleApiGameLibRatio) _The ratio of the current time span._
+
+### getTimeSpanRatioAtTimestamp
+
+Gets the ratio of the time span at the given timestamp.
+
+```javascript
+api.GameLib.Timing.getTimeSpanRatioAtTimestamp(span, timestamp);
+```
+
+| Argument  | Type                                   | Description                        |
+| --------- | -------------------------------------- | ---------------------------------- |
+| span      | [TimeSpan](./ModuleApiGameLibTimeSpan) | TimeSpan instance                  |
+| timestamp | number                                 | The timestamp to get the ratio at. |
+
+**Return** [Ratio](./ModuleApiGameLibRatio) _The ratio of the time span at the given timestamp._
