Hey Ive read them before. im looking for pre-departure delay information please

In both FlightInfo and FlightInfoEx the filed_departuretime can be compared to the actualdeparturetime for determining how close to the original schedule the aircraft departed the runway.

Hey
But is actualdeparturetime avialble before the flight actually depart ?
I saw it contain only zero before the fligth acutally depart and thats too late for me
to be more clear:
I want to know about a delay pre-departure

Thanks !
