I am examining the availability reports and have found some strange 
statistics in Nagios 2.0B2 

I performed a test and have these results from a host for a 24 hour 
period.   The only time that the server was down yesterday was during the 
scheduled reboot.

Scheduled downtime:   20:55 - 22:00
Reboot of Host:  ~14 minutes @ 21:19 

First assumed host state: Host UP
Report Period: Yesterday

Availability Report:
UP:                 23h 44m 28s         98.921% 
DOWN
   Scheduled        0d 0h 8m 43s 0.605% 
   Un-Scheduled     0d 0h 6m 49s 1.079% 

The host log entries shows:

DOWNTIME END End of scheduled downtime 
( Host UP Rest of the time)

Why is there any unscheduled downtime since the downtime was within the 
scheduled downtime?  I have perused the Nagios web site and "googled". 
When I examine services. there duplicating the same thing with scheduled 
outages.

What am I missing?
