Hi,

I have uploaded a new version to avoid expiration.
No changes since the previous draft.

Thanks,
Tal.

Abstract:
   The Network Time Protocol (NTP) allows clients to synchronize to a
   time server using timestamped protocol messages. To faciliate
   accurate timestamping, some implementations use hardware-based
   timestamping engines that integrate the accurate transmission time
   into every outgoing NTP packet during transmission. Since these
   packets are transported over UDP, the UDP checksum field is then
   updated to reflect this modification. This document proposes an
   extension field that includes a 2-octet Checksum Trailer, allowing
   timestamping engines to reflect the checksum modification in the last
   2 octets of the packet rather than in the UDP checksum field. The
   behavior defined in this document is interoperable with existing NTP
   implementations.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
