Nagios stopped checking most of my services!

[Les Fenison]

Well, so far 3 of us with the same problem on the same day.  I have to 
believe it is daylight savings time related. 

My fix is to go click on each service one by one and reschedule.  Then 
they start checking normally again.

I wonder if there is anyway to force an automatic reschedule of all 
services and hosts for next year when this happens again?
