the code part is as follows in base/checks.c

        /* the results for the last check of this service are stale */
        if (expiration_time < current_time) {

                get_time_breakdown((current_time - expiration_time), &days, &hours, &minutes, &seconds);
                get_time_breakdown(freshness_threshold, &tdays, &thours, &tminutes, &tseconds);

                /* log a warning */
                if (log_this == TRUE)
                        logit(NSLOG_RUNTIME_WARNING, TRUE, "Warning: The results of service '%s' on host '%s' are stale by %dd %dh %dm %ds (threshold=%dd %dh %dm %ds).  I'm forcing an immediate check of the service.\n", temp_service->description, temp_service->host_name, days, hours, minutes, seconds, tdays, thours, tminutes, tseconds);

                log_debug_info(DEBUGL_CHECKS, 1, "Check results for service '%s' on host '%s' are stale by %dd %dh %dm %ds (threshold=%dd %dh %dm %ds).  Forcing an immediate check of the service...\n", temp_service->description, temp_service->host_name, days, hours, minutes, seconds, tdays, thours, tminutes, tseconds);

                return FALSE;
        }

by default, the following applies

• expiration_time = last_check + freshness threshold
• expiration_time in the past (< current_time) == stale
• the diff between now and expiration time is shown in the log

if the service has not been checked now, but in the past (event_start > last_check) and its freshness threshold is 0, max_service_check_spread multiplied by the interval is added as additional offset (happens during startup, in order to detect how fast the initial service check (and state + output) must happen.

As a user I would expect that explaination in http://docs.icinga.org/latest/en/servicechecks.html (couldn't find a better place with more generic check behaviour info)
