Guidelines for Defining Packet Timestamps
Tal Mizrahi, Joachim Fabini, Al Morton · 2020
This document specifies guidelines for defining binary packet timestamp formats in networking protocols at various layers. It also presents three recommended timestamp formats. The target audience of this memo includes network protocol designers. It is expected that a new network protocol that requires a packet timestamp will, in most cases, use one of the recommended timestamp formats. If none of the recommended formats fits the protocol requirements, the new protocol specification should specify the format of the packet timestamp according to the guidelines in this document.
