Moodle LMS Timestamp Issue in Grade Sync

Based on the few escalations reported by the customers on the Pearson side, we investigated the issues and identified that the grade sync has failed due to the incorrect timestamp picking by the LMS side.

Given below are the logs for a scenario where during the grade sync, the LMS has taken the time which the grade sync request has submitted from the Pearson end to the Moodle LMS instead of the timestamp in the event payload which is the grade submitted time.

Event sent time from Socket :2022-10-07 19:28:32.767

[
timestamp=2022-10-07T19:26:57.817Z,
scoreGiven=69.0,
scoreMaximum=100.0,
comment=null,
activityProgress=Completed,
gradingProgress=FullyGraded,
userId=xxxxx

]

Current grade in the LMS:

{ "id": "yyyyy", "userId": "xxxxx", "resultScore": 69, "resultMaximum": 100, "timestamp": "2022-10-07T14:28:32-05:00" }

Moodle LMS Version: 2020061504.05
