- class date
- 
  An idealized naive date, assuming the current Gregorian calendar
  always was, and always will be, in effect.
  Attributes: year, month, and day.
- class time
- 
  An idealized time, independent of any particular day, assuming
  that every day has exactly 24*60*60 seconds (there is no notion
  of "leap seconds" here).
  Attributes: hour, minute, second,
              microsecond, and tzinfo.
- class datetime
- 
  A combination of a date and a time.
  Attributes: year, month, day,
              hour, minute, second,
              microsecond, and tzinfo.
- class timedelta
- 
  A duration expressing the difference between two date,
  time, or datetime instances to microsecond
  resolution.
- class tzinfo
- 
  An abstract base class for time zone information objects.  These
  are used by the  datetime and time classes to
  provide a customizable notion of time adjustment (for example, to
  account for time zone and/or daylight saving time).
Objects of these types are immutable.
Objects of the date type are always naive.
An object d of type time or datetime may be
naive or aware.  d is aware if d.tzinfo is not
None and d.tzinfo.utcoffset(d) does not return
None.  If d.tzinfo is None, or if
d.tzinfo is not None but
d.tzinfo.utcoffset(d) returns None, d
is naive.
The distinction between naive and aware doesn't apply to
timedelta objects.
Subclass relationships:

    timedelta
    tzinfo
    time
    date
        datetime
