DKG brought up the question of whether that octet-string should still
include the Unix timestamp like it currently does.
Definitely not. What you want is a means of generating a unique lookup key
(e.g. for a database or hash table) that locates a public key. By mixing a
nonce, the timestamp, into the calculation, you lose the uniqueness, and in
fact the locatability, because the search key is no longer just a hash of the
public key but a hash of the public key and some other metadata that you may
or may not have.
