System time the datagram was send.
Add SOCK_AUX_GET_TIMESTAMP to the bitmask in sock_udp_aux_tx_t::flags to request a transmission timestamp. This bit will be cleared by sock_udp_send_aux if and only if the timestamp was provided. The module
sock_aux_timestamp needs to be selected to use this. The timestamp refers to the transmission of start of frame delimiter or preamble of the frame carrying the datagram and is given in nanoseconds since epoch, unless otherwise documented by the underlying implementation.
