I think the requirement of sending the stamp in GMT is not good. You'd lose
the time zone information. It is possible to convert to a given timezone (be
it Zulu or something else) on the receiver side.

I assume the last sentence was mistyped, and you meant that the relay should
send RFC3339-TIMESTAMP if it receives a message with RFC3339-TIMESTAMP
Btw, why is this a requirement a _MUST_? I think 'SHOULD' is perfectly enough,
a relay can be smart enough to convert from RFC3164 to RFC3339 timestamps if
configured this way. (for example tz information can be added, assuming the
relay is in the same zone as the sender)
