I agree with Alexander -- I think the current documentation is sufficient to describe 'naive' and 'aware' date and time objects.

The sentence "There are two kinds of date and time objects: “naive” and “aware”." is perhaps a bit unfortunate, however. It appears that Anatoly had misinterpreted 'naive' and 'aware' objects to be of different Python types:

> 'naive' and 'aware' are key datetime types

Perhaps the sentence could be changed to something like:

"date and time objects are either 'naive' or 'aware'.
