I'm playing catchup on my INBOX, so apologies in advance, if this has
already been satisfactorily answered...

May I suggest ntpdate(8)?
Find a reliable time server in your region, and once found add it
*early* in your rc.conf(5). Well, ahead of your unbound stanza. ie;
hostname="..."
ifconfig_re0="inet ... netmask ..."
defaultrouter="..."
ntpdate_enable="YES"
ntpdate_hosts="a reliable regional time server"
..
unbound_enable="YES"
..
ALSO. Since you're upstream will, in all likelihood have informed
you of a preferred set of 2 name servers. Place one of them in your
hosts(5) file. This will help ensure that ntpdate(8) can reliably
discover your regional time server.
That should get you where you want to go. :-)
