StartAfterDateTime is not working

Unexpected value is set for StartAfterDateTime in RefreshSchedule.
Is this incorrectly stated in CloudFormation?

CloudFormation:

ExampleRefreshSchedule:
  Type: AWS::QuickSight::RefreshSchedule
  Properties:
    AwsAccountId: !Ref AWS::AccountId
    DataSetId: Example
    Schedule:
      ScheduleId: Example
      RefreshType: FULL_REFRESH
      ScheduleFrequency:
        Interval: HOURLY
        TimeZone: UTC
      StartAfterDateTime: '2023-10-18T07:00:00Z'

I think the StartAfterDateTime is set to 15 minutes later because the date and time I ran the deploy was 2023-10-18T07:03:00Z.

Hey @shinya.sakae !

Could you try updating the format for StartAfterDateTime to match YYYY-MM-DDTHH:MM:SS
