There is a reason for that - money. Measuring the input/output voltage  
requires a mains separated measuring circuit. The micro controller  
used for communication invariably sits on a part of the circuit that  
is isolated from the mains (for obvious reasons). While technically  
this isn't much of a problem, there is a cost penalty to that.

I've renamed these variables in the development version to  
'ups.timer.start' and 'ups.timer.shutdown' for the 'mge-shut' driver  
so that this is consistent with how we use these in other drivers.

@Arnaud: see commit 2257.
