By default all streams use the global locale.
In my applications I add the date_time facets to the global locale at program
startup so e.g. lexical_cast works fine. Of course it would be even better if
lexcial_cast supported locales but it is better than nothing.
If the facet default was the current locale ("%x") I would only need to add
the facets when I need to parse dates.
