localEstimatedOrActualDepartureDateTime property

The estimated time the aircraft plans to pull from the gate or the actual time the aircraft already pulled from the gate.

Note: This is not the runway time. This field should be set if at least one of the below is true: - It differs from the scheduled time. Google will use it to calculate the delay. - The aircraft already pulled from the gate. Google will use it to inform the user when the flight actually departed. This is an ISO 8601 extended format date/time without an offset. Time may be specified up to millisecond precision. eg: 2027-03-05T06:30:00 This should be the local date/time at the airport (not a UTC time). Google will reject the request if UTC offset is provided. Time zones will be calculated by Google based on departure airport. If this is not set, Google will set it based on data from other sources.
