Nut upsdev - Jun 2008 - Best Ferrups reporting uptime in minutes, not seconds

I had a power hiccup yesterday and a server connected to a Best Ferrups
18KVA shutdown.  The problem is that the UPS is reporting remaining
runtime in minutes but nut treats it as seconds (so nut thought it only
had 46 seconds left).

Simple patch:

I don't speak for anybody but myself - that's enough trouble.

The patch looks good at first glance, but by default, NUT should not
use the runtime estimate to initiate a shutdown.

Are you using upssched? Any special parameters to the driver?

Otherwise, NUT will shut down when the UPS signals LB (low battery),
which is a unit-less boolean value.
