Adding new selfReportSessionTime setting

README.md

@@ -52,6 +52,7 @@ The APIs include several settings to customize the functionality of each API:
 | `autoProgress` | false | true/false | In case Sequencing is being used, you can tell the API to automatically throw the `SequenceNext` event.|
 | `logLevel` | 4 | int<br><br>1 => DEBUG<br>2 => INFO<br>3 => WARN<br>4 => ERROR<br>5 => NONE | By default, the APIs only log error messages. |
 | `mastery_override` | false | true/false | (SCORM 1.2) Used to override a module's `cmi.core.lesson_status` so that a pass/fail is determined based on a mastery score and the user's raw score, rather than using whatever status is provided by the module. An example of this would be if a module is published using a `Complete/Incomplete` final status, but the LMS always wants to receive a `Passed/Failed` for quizzes, then we can use this setting to override the given final status. |
+| `selfReportSessionTime` | false | true/false | Should the API override the default `session_time` reported by the module? Useful when modules don't properly report time. |
 | `responseHandler` | function |  | A function to properly tranform the response from the LMS to the correct format. The APIs expect the result from the LMS to be in the following format (errorCode is optional): `{ "result": true, "errorCode": 0 }` |
