    babel.dates
    ~~~~~~~~~~~

    Locale dependent formatting and parsing of dates and times.

    The default locale for the functions in this module is determined by the
    following environment variables, in that order:

     * ``LC_TIME``,
     * ``LC_ALL``, and
     * ``LANG``

    returned comes from ``pytz`` and corresponds to the `tzinfo` interface and

    is ``None`` a local zone object is returned.

    that holds the information about the next timezone transition that's going
    to happen.  For instance this can be used to detect when the next DST
    change is going to happen and how it looks like.

    The transition is calculated relative to the given datetime object.  The
    next transition that follows the date is used.  If a transition cannot
    be found the return value will be `None`.

    Transition information can only be provided for timezones returned by
    the :func:`get_timezone` function.

    :param zone: the timezone for which the transition should be looked up.
                 If not provided the local timezone is used.

    may be specified using a ``datetime`` or `tzinfo` object.

    >>> get_timezone_name(dt, locale='en_US')
    u'Pacific Standard Time'
    >>> get_timezone_name(dt, width='short', locale='en_US')
    u'PST'

    If this function gets passed only a `tzinfo` object and no concrete
    `datetime`,  the returned display name is indenpendent of daylight savings
    time. This can be used for example for selecting timezones, or to set the
    time of events that recur across DST changes:

    >>> tz = get_timezone('America/Los_Angeles')
    >>> get_timezone_name(tz, locale='en_US')
    u'Pacific Time'
    >>> get_timezone_name(tz, 'short', locale='en_US')
    u'PT'

    If no localized display name for the timezone is available, and the timezone
    is associated with a country that uses only a single timezone, the name of
    that country is returned, formatted according to the locale:

    >>> tz = get_timezone('Europe/Berlin')
    >>> get_timezone_name(tz, locale='de_DE')
    u'Mitteleurop\xe4ische Zeit'
    >>> get_timezone_name(tz, locale='pt_BR')
    u'Hor\xe1rio da Europa Central'

    On the other hand, if the country uses multiple timezones, the city is also
    included in the representation:

    >>> tz = get_timezone('America/St_Johns')
    >>> get_timezone_name(tz, locale='de_DE')
    u'Neufundland-Zeit'

    Note that short format is currently not supported for all timezones and
    all locales.  This is partially because not every timezone has a short
    code in every locale.  In that case it currently falls back to the long
    format.

                         independent of daylight savings time; if `None`, the

    >>> format_time(t, format='short', locale='de_DE')
    u'15:30'

    If you don't want to use the locale default formats, you can specify a
    custom time pattern:

    >>> format_time(t, "hh 'o''clock' a", locale='en')
    u"03 o'clock PM"

    For any pattern requiring the display of the time-zone a
    timezone has to be specified explicitly:

    >>> t = datetime(2007, 4, 1, 15, 30)
    >>> tzinfo = get_timezone('Europe/Paris')
    >>> t = tzinfo.localize(t)

    ...             locale='en')
    u"09 o'clock AM, Eastern Daylight Time"

    As that example shows, when this function gets passed a
    ``datetime.datetime`` value, the actual time in the formatted string is
    adjusted to the timezone specified by the `tzinfo` parameter. If the
    ``datetime`` is "naive" (i.e. it has no associated timezone information),
    it is assumed to be in UTC.

    These timezone calculations are **not** performed if the value is of type
    ``datetime.time``, as without date information there's no way to determine
    what a given time would translate to in a different timezone without
    information about whether daylight savings time is in effect or not. This
    means that time values are left as-is, and the value of the `tzinfo`
    parameter is only used to display the timezone name if needed:

    >>> t = time(15, 30)
    >>> format_time(t, format='full', tzinfo=get_timezone('Europe/Paris'),
    ...             locale='fr_FR')
    u'15:30:00 heure normale de l\u2019Europe centrale'
    >>> format_time(t, format='full', tzinfo=get_timezone('US/Eastern'),
    ...             locale='en_US')
    u'3:30:00 PM Eastern Standard Time'

    :param time: the ``time`` or ``datetime`` object; if `None`, the current
                 time in UTC is used
    :param format: one of "full", "long", "medium", or "short", or a custom
                   date/time pattern
    :param tzinfo: the time-zone to apply to the time for display
    :param locale: a `Locale` object or a locale identifier

siReturn a time delta according to the rules of the given locale.

    >>> format_timedelta(timedelta(weeks=12), locale='en_US')
    u'3 months'
    >>> format_timedelta(timedelta(seconds=1), locale='es')
    u'1 segundo'

    The granularity parameter can be provided to alter the lowest unit
    presented, which defaults to a second.

    >>> format_timedelta(timedelta(hours=3), granularity='day',
    ...                  locale='en_US')
    u'1 day'

    The threshold parameter can be used to determine at which value the
    presentation switches to the next higher unit. A higher threshold factor
    means the presentation will switch later. For example:

    >>> format_timedelta(timedelta(hours=23), threshold=0.9, locale='en_US')
    u'1 day'
    >>> format_timedelta(timedelta(hours=23), threshold=1.1, locale='en_US')
    u'23 hours'

    In addition directional information can be provided that informs
    the user if the date is in the past or in the future:

    >>> format_timedelta(timedelta(hours=1), add_direction=True)
    u'In 1 hour'
    >>> format_timedelta(timedelta(hours=-1), add_direction=True)
    u'1 hour ago'

    :param delta: a ``timedelta`` object representing the time difference to
                  format, or the delta in seconds as an `int` value
    :param granularity: determines the smallest unit that should be displayed,
                        the value can be one of "year", "month", "week", "day",
                        "hour", "minute" or "second"
    :param threshold: factor that determines at which point the presentation
                      switches to the next higher unit
    :param add_direction: if this flag is set to `True` the return value will
                          include directional information.  For instance a
                          positive timedelta will include the information about
                          it being in the future, a negative will be information
                          about the value being in the past.
    :param format: the format (currently only "medium" and "short" are supported)
    :param locale: a `Locale` object or a locale identifier
