        Wrapper for :func:`ZoneInfoFile.zones.get`. This is a convenience method
        for retrieving zones from the zone dictionary.

        :param name:
            The name of the zone to retrieve. (Generally IANA zone names)

        :param default:
            The value to return in the event of a missing key.

    This is a convenience function which provides a :class:`ZoneInfoFile`
    instance using the data provided by the ``dateutil`` package. By default, it
    caches a single instance of the ZoneInfoFile object and returns that.

    :param new_instance:
        If ``True``, a new instance of :class:`ZoneInfoFile` is instantiated and
        used as the cached instance for the next call. Otherwise, new instances
        are created only as necessary.

    :return:
        Returns a :class:`ZoneInfoFile` object.

    This retrieves a time zone from the local zoneinfo tarball that is packaged
    with dateutil.

    :param name:
        An IANA-style time zone name, as found in the zoneinfo file.

    :return:
        Returns a :class:`dateutil.tz.tzfile` time zone object.

    .. warning::
        It is generally inadvisable to use this function, and it is only
        provided for API compatibility with earlier versions. This is *not*
        equivalent to ``dateutil.tz.gettz()``, which selects an appropriate
        time zone based on the inputs, favoring system zoneinfo. This is ONLY
        for accessing the dateutil-specific zoneinfo (which may be out of
        date compared to the system zoneinfo).

    .. deprecated:: 2.6
        If you need to use a specific zoneinfofile over the system zoneinfo,
        instantiate a :class:`dateutil.zoneinfo.ZoneInfoFile` object and call
        :func:`dateutil.zoneinfo.ZoneInfoFile.get(name)` instead.

        Use :func:`get_zonefile_instance` to retrieve an instance of the
        dateutil-provided zoneinfo.
    zzoneinfo.gettz() will be removed in future versions, to use the dateutil-provided zoneinfo files, instantiate a ZoneInfoFile object and use ZoneInfoFile.zones.get() instead. See the documentation for details.r   )
