I would agree - that requirement sounds strange.
I suggest you ask the people responsible for this document
about the thinking behind it.
This mailing list is specifically for support of the Net-SNMP suite.
Individual members may have some knowledge of the development
of the SNMP protocol over the years, but we don't have any special
information about other groups' use of SNMP, or their design processes.
If you have a question about an EBU document, try asking the EBU!

PS: If push came to shove, you could always include the hrSystemDate.0
varbind as part of the notification payload. That would link the trap
with an absolute time, as required.
