We are not talking about PTP, but about specific to RDMA timestamp mechanism which is added to the CQE (completion queue entry) per-user request when he/she creates CQ (completion queue). User has an option to choose the format of it for every QP/RQ/SQ. https://github.com/linux-rdma/rdma-core/blob/master/libibverbs/man/ibv_create_cq_ex.3#L44 Thanks
