This module offers a generic date/time string parser which is able to parse
most known formats to represent a date and/or time.

This module attempts to be forgiving with regards to unlikely input formats,
returning a datetime object even for dates which are ambiguous. If an element
of a date/time stamp is omitted, the following rules are applied:

- If AM or PM is left unspecified, a 24-hour clock is assumed, however, an hour
  on a 12-hour clock (``0 <= hour <= 12``) *must* be specified if AM or PM is
  specified.
- If a time zone is omitted, a timezone-naive datetime is returned.

If any other elements are missing, they are taken from the
:class:`datetime.datetime` object passed to the parameter ``default``. If this
results in a day number exceeding the valid number of days per month, the
value falls back to the end of the month.

        This function breaks the time string into lexical units (tokens), which
        can be parsed by the parser. Lexical units are demarcated by changes in
        the character set, so any continuous string of letters is considered
        one unit, any continuous string of numbers is considered one unit.

        The main complication arises from the fact that dots ('.') can be used
        both as separators (e.g. "Sep.20.2009") or decimal points (e.g.
        "4:30:21.447"). As such, it is necessary to read the full context of
        any dot-separated strings before breaking it into tokens; as such, this
        function maintains a "token stack", for when the ambiguous context
        demands that multiple tokens be parsed at once.

        Whether to interpret the first value in an ambiguous 3-integer date
        (e.g. 01/05/09) as the day (``True``) or month (``False``). If

        Parse the date/time string into a :class:`datetime.datetime` object.

        :param timestr:
            Any date/time string using the supported formats.

        :param default:
            The default datetime object, if this is a datetime object and not
            ``None``, elements specified in ``timestr`` replace elements in the
            default object.

        :param ignoretz:
            If set ``True``, time zones in parsed strings are ignored and a
            naive :class:`datetime.datetime` object is returned.

        :param tzinfos:
            Additional time zone names / aliases which may be present in the
            string. This argument maps time zone names (and optionally offsets
            from those time zones) to time zones. This parameter can be a
            dictionary with timezone aliases mapping time zone names to time
            zones or a function taking two parameters (``tzname`` and
            ``tzoffset``) and returning a time zone.

            The timezones to which the names are mapped can be an integer
            offset from UTC in seconds or a :class:`tzinfo` object.

            .. doctest::

            This parameter is ignored if ``ignoretz`` is set.

        :param \*\*kwargs:
            Keyword arguments as passed to ``_parse()``.

        :return:
            Returns a :class:`datetime.datetime` object or, if the
            ``fuzzy_with_tokens`` option is ``True``, returns a tuple, the
            first element being a :class:`datetime.datetime` object, the second
            a tuple containing the fuzzy tokens.

        :raises ParserError:
            Raised for invalid or unknown string format, if the provided
            :class:`tzinfo` is not in a valid format, or if an invalid date
            would be created.

        :raises TypeError:
            Raised for non-string or character stream input.

        :raises OverflowError:
            Raised if the parsed date exceeds the largest valid C integer on

        Private method which performs the heavy lifting of parsing, called from
        ``parse()``, which passes on its ``kwargs`` to this function.

        :param timestr:
            The string to parse.

        :param dayfirst:
            Whether to interpret the first value in an ambiguous 3-integer date
            (e.g. 01/05/09) as the day (``True``) or month (``False``). If
            ``yearfirst`` is set to ``True``, this distinguishes between YDM
            and YMD. If set to ``None``, this value is retrieved from the
            current :class:`parserinfo` object (which itself defaults to
            ``False``).

        :param yearfirst:
            Whether to interpret the first value in an ambiguous 3-integer date
            (e.g. 01/05/09) as the year. If ``True``, the first number is taken
            to be the year, otherwise the last number is taken to be the year.
            If this is set to ``None``, the value is retrieved from the current
            :class:`parserinfo` object (which itself defaults to ``False``).

        :param fuzzy:
            Whether to allow fuzzy parsing, allowing for string like "Today is
            January 1, 2047 at 8:21:00AM".

        :param fuzzy_with_tokens:
            If ``True``, ``fuzzy`` is automatically set to True, and the parser
            will return a tuple where the first element is the parsed
            :class:`datetime.datetime` datetimestamp and the second element is
            a tuple containing the portions of the string which were ignored:

    Parse a string in one of the supported formats, using the
    ``parserinfo`` parameters.

    :param timestr:
        A string containing a date/time stamp.

    :param parserinfo:
        A :class:`parserinfo` object containing parameters for the parser.
        If ``None``, the default arguments to the :class:`parserinfo`
        constructor are used.

    The ``**kwargs`` parameter takes the following keyword arguments:

    :param default:
        The default datetime object, if this is a datetime object and not
        ``None``, elements specified in ``timestr`` replace elements in the
        default object.

    :param ignoretz:
        If set ``True``, time zones in parsed strings are ignored and a naive
        :class:`datetime` object is returned.

    :param tzinfos:
        Additional time zone names / aliases which may be present in the
        string. This argument maps time zone names (and optionally offsets
        from those time zones) to time zones. This parameter can be a
        dictionary with timezone aliases mapping time zone names to time
        zones or a function taking two parameters (``tzname`` and
        ``tzoffset``) and returning a time zone.

        The timezones to which the names are mapped can be an integer
        offset from UTC in seconds or a :class:`tzinfo` object.

        .. doctest::
           :options: +NORMALIZE_WHITESPACE

            >>> from dateutil.parser import parse
            >>> from dateutil.tz import gettz
            >>> tzinfos = {"BRST": -7200, "CST": gettz("America/Chicago")}
            >>> parse("2012-01-19 17:21:00 BRST", tzinfos=tzinfos)
            datetime.datetime(2012, 1, 19, 17, 21, tzinfo=tzoffset(u'BRST', -7200))
            >>> parse("2012-01-19 17:21:00 CST", tzinfos=tzinfos)
            datetime.datetime(2012, 1, 19, 17, 21,
                              tzinfo=tzfile('/usr/share/zoneinfo/America/Chicago'))

        This parameter is ignored if ``ignoretz`` is set.

    :param dayfirst:
        Whether to interpret the first value in an ambiguous 3-integer date
        (e.g. 01/05/09) as the day (``True``) or month (``False``). If
        ``yearfirst`` is set to ``True``, this distinguishes between YDM and
        YMD. If set to ``None``, this value is retrieved from the current
        :class:`parserinfo` object (which itself defaults to ``False``).

    :param yearfirst:
        Whether to interpret the first value in an ambiguous 3-integer date
        (e.g. 01/05/09) as the year. If ``True``, the first number is taken to
        be the year, otherwise the last number is taken to be the year. If
        this is set to ``None``, the value is retrieved from the current
        :class:`parserinfo` object (which itself defaults to ``False``).

    :param fuzzy:
        Whether to allow fuzzy parsing, allowing for string like "Today is
        January 1, 2047 at 8:21:00AM".

    :param fuzzy_with_tokens:
        If ``True``, ``fuzzy`` is automatically set to True, and the parser
        will return a tuple where the first element is the parsed
        :class:`datetime.datetime` datetimestamp and the second element is
        a tuple containing the portions of the string which were ignored:

        .. doctest::

            >>> from dateutil.parser import parse
            >>> parse("Today is January 1, 2047 at 8:21:00AM", fuzzy_with_tokens=True)
            (datetime.datetime(2047, 1, 1, 8, 21), (u'Today is ', u' ', u'at '))

    :return:
        Returns a :class:`datetime.datetime` object or, if the
        ``fuzzy_with_tokens`` option is ``True``, returns a tuple, the
        first element being a :class:`datetime.datetime` object, the second
        a tuple containing the fuzzy tokens.

    :raises ValueError:
        Raised for invalid or unknown string format, if the provided
        :class:`tzinfo` is not in a valid format, or if an invalid date
        would be created.

    :raises OverflowError:
        Raised if the parsed date exceeds the largest valid C integer on
        your system.
