Well, if you have questions just ask.  There are many reasons why there isn't 
more documenation of the generic part of the library -- the primary ones 
being I don't believe I'm done modifying it and that it is an implementation 
detail for 98% of the users.

No, ptime is a non-adjusted time representation.  So it can be used to 
represent either UTC or a local time.  However, if it is a local time the 
user is required to keep that information externally.  In the next release of 
the library there will be a local_date_time and time_zone classes that 
provide full support for local time representations.

Yes, it is currently limited to the 2 specified resolutions.  However, I have 
helped, and will help anyone that needs other resolutions.  There is some 
refactoring and that needs to be done before this is offered as a documented 
feature of the library.
