API rejecting valid datetime objects which comply with ISO-8601

Hello, this is a bug report regarding datetime submission, where there are issues sending requests to many endpoints which are utc formatted:
The API rejects valid ISO-8601 values such as 2026-08-28T03:30:00+00:00 and only accepts 2026-08-28T03:30:00.000Z.

// this is a working example of the appointment infor endpoint via postman

{
  "Pte": "Appointment",
  "ScheduledStart": "2026-08-28T03:30:00.000Z",
  "WorkOrderId": 123456,
  "MessageId": "Booking info"
}

// this is an example of a payload which fails, even though it conforms to ISO-8601 standards
{
  "Pte": "Appointment",
  "ScheduledStart": "2026-08-28T13:30:00+10:00",
  "WorkOrderId": 123456,
  "MessageId": "Booking info"
}
