Just a coding style question: wouldn't it make more sense for a 
USDateTimeParser to be a subclass of DateTimeParser?  I know adapters 
are "hip" these days :-) but it seems much more natural to write a 
subclass in this situation.

Now, if you had hypothetical TextualDateTime objects lying around, you 
might want to register an adapter for ITextualDateTime that can convert 
to IDateTimeParser.  The registered adapter would be either the US or 
generic version.
