Yes of course ... one class template with different instances. Yet different
instances of the same class template are different types so compilers can
help to avoid errors ...

But ... to make the discussion more substantial and to give the authors
of boost::date_time the acknowledgement that they surely deserve I am
going to study the documentation more closely first before making
more suggestions.

As a first reading shows customization of resolution and iteration on
different granularity levels are sagely provided.
