There was a time when Nagios did non-aggregated updates to the status
file. Meaning as each service/host was checked, the status file was
updated. This meant each status entry could have a different last
update time. Obviously, this doesn't scale very well, and
non-aggregated status updates were dropped.
Short answer is that this functionality can probably be removed now.
