Use the time for the last non-running status to determine
whether the restart did not occur as expected. The
current timestamp only accounts for when the running
status was seen, however, the restart would have always
occurred in between the previous check and latest check.
Therefore, it makes more sense to use the previous check
to determine whether a failure was seen from the restart
monitor not restarting as expected.
