            Offsets found in the registry are generally of the form

    Time zone object created from the zone info in the Windows registry

    These are similar to :py:class:`dateutil.tz.tzrange` objects in that
    the time zone data is provided in the format of a single offset rule
    for either 0 or 2 time zone transitions per year.

    :param: name
        The name of a Windows time zone key, e.g. "Eastern Standard Time".
        The full list of keys can be retrieved with :func:`tzwin.list`.

    Class representing the local time zone information in the Windows registry

    While :class:`dateutil.tz.tzlocal` makes system calls (via the :mod:`time`
    module) to retrieve time zone information, ``tzwinlocal`` retrieves the
    rules directly from the Windows registry and creates an object like
    :class:`dateutil.tz.tzwin`.

    Because Windows does not have an equivalent of :func:`time.tzset`, on
    Windows, :class:`dateutil.tz.tzlocal` instances will always reflect the
    time zone settings *at the time that the process was started*, meaning
    changes to the machine's time zone settings during the run of a program
    on Windows will **not** be reflected by :class:`dateutil.tz.tzlocal`.
    Because ``tzwinlocal`` reads the registry directly, it is unaffected by
    this issue.
