There's a function in core.time:

Duration days(int n);


D functions f(x, t...) can also be called x.f(t) (or x.f without 
parameters if there's no additional arguments).

This works on all types, it is called uniform function call 
syntax, or UFCS. It lets us extend other things with new methods.
