DESCRIPTION

       Pass  a  pointer to a double to receive the time, in seconds, it took from the start until
       the file transfer is just about to begin. This  includes  all  pre-transfer  commands  and
       negotiations that are specific to the particular protocol(s) involved. It does not involve
       the sending of the protocol- specific request that triggers a transfer.
