Not auditctl, but maybe ausearch:
ausearch --start boot -m daemon_start -i

Or...
systemctl status auditd.service | grep Active

And if you need this in the epoch:
date --date="$(systemctl status auditd.service|grep Active|awk '{printf "%s 
%s", $6, $7}')" +"%s"

That might be one issue with using ausearch...it might have scrolled away. 
Maybe this could be collected at start and printed as part of the auditd 
state report? I could see this being useful information for various reasons.

systemctl should be able to get you the info you need. I might add this info 
to the state report, though.
