        Parsing datetimes
        -----------------
        
        To parse a typical ISO 8601 datetime string::
        
          >>> import aniso8601
          >>> from attotimebuilder import AttoTimeBuilder
          >>> aniso8601.parse_datetime('1977-06-10T12:00:00', builder=AttoTimeBuilder)
          attotime.attodatetime(1977, 6, 10, 12, 0, 0, 0, 0)
        
        Alternative delimiters can be specified, for example, a space::
        
          >>> aniso8601.parse_datetime('1977-06-10 12:00:00', delimiter=' ', builder=AttoTimeBuilder)
          attotime.attodatetime(1977, 6, 10, 12, 0, 0, 0, 0)
        
        Both UTC (Z) and UTC offsets for timezones are supported::
        
          >>> aniso8601.parse_datetime('1977-06-10T12:00:00Z', builder=AttoTimeBuilder)
          attotime.attodatetime(1977, 6, 10, 12, 0, 0, 0, 0, +0:00:00 UTC)
          >>> aniso8601.parse_datetime('1979-06-05T08:00:00-08:00', builder=AttoTimeBuilder)
          attotime.attodatetime(1979, 6, 5, 8, 0, 0, 0, 0, -8:00:00 UTC)
        
        Leap seconds are explicitly not supported::
        
          >>> aniso8601.parse_datetime('2018-03-06T23:59:60', builder=AttoTimeBuilder)
          Traceback (most recent call last):
            File "<stdin>", line 1, in <module>
            File "/home/nielsenb/Jetfuse/attotimebuilder/python2/lib/python2.7/site-packages/aniso8601/time.py", line 131, in parse_datetime
              return builder.build_datetime(datepart, timepart)
            File "attotimebuilder/__init__.py", line 120, in build_datetime
              cls._build_object(time))
            File "/home/nielsenb/Jetfuse/attotimebuilder/python2/lib/python2.7/site-packages/aniso8601/builder.py", line 71, in _build_object
              ss=parsetuple[2], tz=parsetuple[3])
            File "attotimebuilder/__init__.py", line 73, in build_time
              raise LeapSecondError('Leap seconds are not supported.')
          aniso8601.exceptions.LeapSecondError: Leap seconds are not supported.
        
        Parsing dates
        -------------
        
        There is no :code:`attodate` type, so native Python :code:`datetime.date` objects are returned.
        
        To parse a date represented in an ISO 8601 string::
        
          >>> import aniso8601
          >>> from attotimebuilder import AttoTimeBuilder
          >>> aniso8601.parse_date('1984-04-23', builder=AttoTimeBuilder)
          datetime.date(1984, 4, 23)
        
        Basic format is supported as well::
        
          >>> aniso8601.parse_date('19840423', builder=AttoTimeBuilder)
          datetime.date(1984, 4, 23)
        
        To parse a date using the ISO 8601 week date format::
        
          >>> aniso8601.parse_date('1986-W38-1', builder=AttoTimeBuilder)
          datetime.date(1986, 9, 15)
        
        To parse an ISO 8601 ordinal date::
        
          >>> aniso8601.parse_date('1988-132', builder=AttoTimeBuilder)
          datetime.date(1988, 5, 11)
        
        Parsing times
        -------------
        
        To parse a time formatted as an ISO 8601 string::
        
          >>> import aniso8601
          >>> from attotimebuilder import AttoTimeBuilder
          >>> aniso8601.parse_time('11:31:14', builder=AttoTimeBuilder)
          attotime.attotime(11, 31, 14, 0, 0)
        
        As with all of the above, basic format is supported::
        
          >>> aniso8601.parse_time('113114', builder=AttoTimeBuilder)
          attotime.attotime(11, 31, 14, 0, 0)
        
        A UTC offset can be specified for times::
        
          >>> aniso8601.parse_time('17:18:19-02:30', builder=AttoTimeBuilder)
          attotime.attotime(17, 18, 19, 0, 0, -2:30:00 UTC)
          >>> aniso8601.parse_time('171819Z', builder=AttoTimeBuilder)
          attotime.attotime(17, 18, 19, 0, 0, +0:00:00 UTC)
        
        Reduced accuracy is supported::
        
          >>> aniso8601.parse_time('21:42', builder=AttoTimeBuilder)
          attotime.attotime(21, 42, 0, 0, 0)
          >>> aniso8601.parse_time('22', builder=AttoTimeBuilder)
          attotime.attotime(22, 0, 0, 0, 0)
        
        A decimal fraction is always allowed on the lowest order element of an ISO 8601 formatted time::
        
          >>> aniso8601.parse_time('22:33.5', builder=AttoTimeBuilder)
          attotime.attotime(22, 33, 30, 0, 0.0)
          >>> aniso8601.parse_time('23.75', builder=AttoTimeBuilder)
          attotime.attotime(23, 45, 0, 0, 0.00)
        
        Leap seconds are explicitly not supported and attempting to parse one raises a :code:`LeapSecondError`::
        
          >>> aniso8601.parse_time('23:59:60', builder=AttoTimeBuilder)
          Traceback (most recent call last):
            File "<stdin>", line 1, in <module>
            File "/home/nielsenb/Jetfuse/attotimebuilder/python2/lib/python2.7/site-packages/aniso8601/time.py", line 116, in parse_time
              return _RESOLUTION_MAP[get_time_resolution(timestr)](timestr, tz, builder)
            File "/home/nielsenb/Jetfuse/attotimebuilder/python2/lib/python2.7/site-packages/aniso8601/time.py", line 165, in _parse_second_time
              return builder.build_time(hh=hourstr, mm=minutestr, ss=secondstr, tz=tz)
            File "attotimebuilder/__init__.py", line 73, in build_time
              raise LeapSecondError('Leap seconds are not supported.')
          aniso8601.exceptions.LeapSecondError: Leap seconds are not supported.
        
        Parsing durations
        -----------------
        
        To parse a duration formatted as an ISO 8601 string::
        
          >>> import aniso8601
          >>> from attotimebuilder import AttoTimeBuilder
          >>> aniso8601.parse_duration('P1Y2M3DT4H54M6S', builder=AttoTimeBuilder)
          attotime.attotimedelta(428, 17646)
        
        Reduced accuracy is supported::
        
          >>> aniso8601.parse_duration('P1Y', builder=AttoTimeBuilder)
          attotime.attotimedelta(365)
        
        A decimal fraction is allowed on the lowest order element::
        
          >>> aniso8601.parse_duration('P1YT3.5M', builder=AttoTimeBuilder)
          attotime.attotimedelta(365, 210)
        
        The decimal fraction can be specified with a comma instead of a full-stop::
        
          >>> aniso8601.parse_duration('P1YT3,5M', builder=AttoTimeBuilder)
          attotime.attotimedelta(365, 210)
        
        Parsing a duration from a combined date and time is supported as well::
        
          >>> aniso8601.parse_duration('P0001-01-02T01:30:5', builder=AttoTimeBuilder)
          attotime.attotimedelta(397, 5405)
        
        Parsing intervals
        -----------------
        
        To parse an interval specified by a start and end::
        
          >>> import aniso8601
          >>> from attotimebuilder import AttoTimeBuilder
          >>> aniso8601.parse_interval('2007-03-01T13:00:00/2008-05-11T15:30:00', builder=AttoTimeBuilder)
          (attotime.attodatetime(2007, 3, 1, 13, 0, 0, 0, 0), attotime.attodatetime(2008, 5, 11, 15, 30, 0, 0, 0))
        
        Intervals specified by a start time and a duration are supported::
        
          >>> aniso8601.parse_interval('2007-03-01T13:00:00/P1Y2M10DT2H30M', builder=AttoTimeBuilder)
          (attotime.attodatetime(2007, 3, 1, 13, 0, 0, 0, 0), attotime.attodatetime(2008, 5, 9, 15, 30, 0, 0, 0))
        
        A duration can also be specified by a duration and end time, note that no :code:`attodate` type exists, so dates are returned as native :code:`datetime.date` objects::
        
          >>> aniso8601.parse_interval('P1M/1981-04-05', builder=AttoTimeBuilder)
          (datetime.date(1981, 4, 5), datetime.date(1981, 3, 6))
        
        Notice that the result of the above parse is not in order from earliest to latest. If sorted intervals are required, simply use the :code:`sorted` keyword as shown below::
        
          >>> sorted(aniso8601.parse_interval('P1M/1981-04-05', builder=AttoTimeBuilder))
          [datetime.date(1981, 3, 6), datetime.date(1981, 4, 5)]
        
        The end of an interval is returned as a :code:`attodatetime` when required to maintain the resolution specified by a duration, even if the duration start is given as a date::
        
          >>> aniso8601.parse_interval('2014-11-12/PT4H54M6.5S', builder=AttoTimeBuilder)
          (datetime.date(2014, 11, 12), attotime.attodatetime(2014, 11, 12, 4, 54, 6, 500000, 0.0))
          >>> aniso8601.parse_interval('2007-03-01/P1.5D', builder=AttoTimeBuilder)
          (datetime.date(2007, 3, 1), attotime.objects.attodatetime(2007, 3, 2, 12, 0, 0, 0, 0.0))
        
        Repeating intervals are supported as well, and return a generator::
        
          >>> aniso8601.parse_repeating_interval('R3/1981-04-05/P1D', builder=AttoTimeBuilder)
          <generator object _date_generator at 0x7fba29feed20>
          >>> list(aniso8601.parse_repeating_interval('R3/1981-04-05/P1D', builder=AttoTimeBuilder))
          [datetime.date(1981, 4, 5), datetime.date(1981, 4, 6), datetime.date(1981, 4, 7)]
        
        Repeating intervals are allowed to go in the reverse direction::
        
          >>> list(aniso8601.parse_repeating_interval('R2/PT1H2M/1980-03-05T01:01:00', builder=AttoTimeBuilder))
          [attotime.attodatetime(1980, 3, 5, 1, 1, 0, 0, 0), attotime.attodatetime(1980, 3, 4, 23, 59, 0, 0, 0)]
        
        Unbounded intervals are also allowed (Python 2)::
        
          >>> result = aniso8601.parse_repeating_interval('R/PT1H2M/1980-03-05T01:01:00', builder=AttoTimeBuilder)
          >>> result.next()
          attotime.attodatetime(1980, 3, 5, 1, 1, 0, 0, 0)
          >>> result.next()
          attotime.attodatetime(1980, 3, 4, 23, 59, 0, 0, 0)
        
        or for Python 3::
        
          >>> result = aniso8601.parse_repeating_interval('R/PT1H2M/1980-03-05T01:01:00', builder=AttoTimeBuilder)
          >>> next(result)
          attotime.attodatetime(1980, 3, 5, 1, 1, 0, 0, 0)
          >>> next(result)
          attotime.attodatetime(1980, 3, 4, 23, 59, 0, 0, 0)
        
        The above treat years as 365 days and months as 30 days. Fractional months and years are supported accordingly::
        
          >>> aniso8601.parse_interval('P1.1Y/2001-02-28', builder=AttoTimeBuilder)
          (datetime.date(2001, 2, 28), datetime.date(2000, 1, 23))
          >>> aniso8601.parse_interval('2001-02-28/P1Y2.5M', builder=AttoTimeBuilder)
          (datetime.date(2001, 2, 28), datetime.date(2002, 5, 14))
