Sorry for the confusion, i tested 2.0 from debian etch and 2.2 from  
debian testing.

Why is this output not so elaborated like the apcsmart one?

So, could you explain me the strange behaviour? Why the value of the  
variable is never the one you set, and what kind of unit are used?  
Minutes? Hours?

Now i'm confused. How can i set delays to the different ups? I need to  
boot my devices in one specific order, and the only way to do that is  
with boot delays at the ups.
Powerchute from APC can do that, and as far i can remember, so can  
apcupsd.

I will try the new version Monday.

Thanks for your help.
