Hmm, the idea of the ``.add()`` and ``.subtract()`` methods is tempting, but I not sure it is a good idea to add new methods to the ndarray object that are meant to be used with just the date/time dtype.

I'm afraid that I'm -1 here.

I fully agree with Francesc, .add and .subtract will be quite confusing. About inplace conversions, the right-end (other) is cast to the type of the left end (self) by default following the basic rule of casting when there's no ambiguity and raising an exception otherwise ?
