whereas to the ietf list, it is delayed by the best part of a day.

I can see the latter snippet features a very long delay. However,
you snipped those signatures one field too soon. From the header
of the message you wrote I get

This is only a few seconds delay, but applying epoch logic, i.e.,
0x4ea129e8 = 1319184872 = 2011-10-21T01:14:32+07:00, I can see DKIM
contribution. IIRC, opendkim gets the time(&now) for that timestamp
at end-of-header, before beginning to compute the body hash.
