Yeah, there has to be a better way to document these functions. I 
guess I could have figured out that there is a Duration struct 
from this

opBinary(string op, D)(in D duration) if ((op == "+" || op == 
"-") && (is(Unqual!D == Duration) || is(Unqual!D == 
TickDuration)))

but (string op, D) -> (in D duration) -> is(Unqual!D == Duration) 
is something that would be rejected from Boost because it's too 
complicated for C++.
