Abstract Abstract
This document specifies guidelines for defining binary packet This document specifies guidelines for defining binary packet
timestamp formats in networking protocols at various layers. It also timestamp formats in networking protocols at various layers. It also
presents three recommended timestamp formats. The target audience of presents three recommended timestamp formats. The target audience of
this memo includes network protocol designers. It is expected that a this memo includes network protocol designers. It is expected that a
new network protocol that requires a packet timestamp will, in most new network protocol that requires a packet timestamp will, in most
cases, use one of the recommended timestamp formats. If none of the cases, use one of the recommended timestamp formats. If none of the
recommended formats fits the protocol requirements, the new protocol recommended formats fits the protocol requirements, the new protocol
