As Dave pointed out, this isn't a bug; -2 is of type int, and it gets 
promoted to unsigned long for the division. This (correctly) produces a 
large value.

I haven't looked at to_duration, but I remember struggling with the 
analogous code in our implementation. Mixing signed and unsigned types can 
be hazardous to your sanity.
