pfblockerng/dnsbl.log timestamp resolution?

[fabrizior]

/var/log/pfblockerng/dnsbl.log has thousands of log entries a second.
Is it possible to extend the timestamp to log millisecond resolution?

e.g.
DNSBL Reject HTTPS,Mar 14 17:10:04.0000,graph.instagram.com

I realize the [stupid] limitation that the FreeBSD "date" command has, lacking the %N format.
$ date +%H:%M:%S.%N
17:36:01.N

That being the case, the system does have a proper clock... as demonstrated:
$ perl -MTime::HiRes=gettimeofday -MPOSIX=strftime -e '($s,$us) = gettimeofday(); printf "%d.%06d\n", $s, $us' && date +%s
