Rejection of Telegraphic Proposal Modification as Untimely

A company protested rejection of its amended proposal as beg late. Its telegraphic proposal modification was time-stamped at Air Force base 27 minutes after designated time for receipt of proposals. Transmission time of TWX message was prior to deadline, but the only acceptable evidence of timely receipt, where no evidence existed regarding time-stamp or receiving equipment malfunction, was agency time/date stamp. The protest was denied.
