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``

>>> get_timezone_name(dt, locale='en_US', return_zone=True)
'America/Los_Angeles'
>>> 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.

u'3:30:00 PM'
>>> 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)
>>> format_time(t, format='full', tzinfo=tzinfo, locale='fr_FR')

>>> format_time(t, "hh 'o''clock' a, zzzz", tzinfo=get_timezone('US/Eastern'),
... 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 d\u2019Europe centrale'

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, locale='en')
u'in 1 hour'
>>> format_timedelta(timedelta(hours=-1), add_direction=True, locale='en')

The format parameter controls how compact or wide the presentation is:
>>> format_timedelta(timedelta(hours=3), format='short', locale='en')
u'3 hr'
>>> format_timedelta(timedelta(hours=3), format='narrow', locale='en')
u'3h'
: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, can be "narrow", "short" or "long". (
"medium" is deprecated, currently converted to "long" to
maintain compatibility)

:param time: The time to inspect.
:param tzinfo: The timezone for the time. See ``format_time``.
