This module offers timezone implementations subclassing the abstract
:py:class:`datetime.tzinfo` type. There are classes to handle tzfile format
files (usually are in :file:`/etc/localtime`, :file:`/usr/share/zoneinfo`,
etc), TZ environment string (in all known formats), given ranges (with help
from relative deltas), local machine timezone, fixed offset timezone, and UTC
timezone.

This is a tzinfo object that represents the UTC time zone.
**Examples:**
.. doctest::
>>> from datetime import *
>>> from dateutil.tz import *
>>> datetime.now()
datetime.datetime(2003, 9, 27, 9, 40, 1, 521290)
>>> datetime.now(tzutc())
datetime.datetime(2003, 9, 27, 12, 40, 12, 156379, tzinfo=tzutc())
>>> datetime.now(tzutc()).tzname()
'UTC'
.. versionchanged:: 2.7.0
``tzutc()`` is now a singleton, so the result of ``tzutc()`` will
always return the same object.
.. doctest::
>>> from dateutil.tz import tzutc, UTC
>>> tzutc() is tzutc()
True
>>> tzutc() is UTC
True

This is a ``tzinfo`` subclass that allows one to use the ``tzfile(5)``
format timezone files to extract current and historical zone information.
:param fileobj:
This can be an opened file stream or a file name that the time zone
information can be read from.
:param filename:
This is an optional parameter specifying the source of the time zone
information in the event that ``fileobj`` is a file object. If omitted
and ``fileobj`` is a file stream, this parameter will be set either to
``fileobj``'s ``name`` attribute or to ``repr(fileobj)``.
See `Sources for Time Zone and Daylight Saving Time Data
`_ for more information.
Time zone files can be compiled from the `IANA Time Zone database files
`_ with the `zic time zone compiler
`_
.. note::
Only construct a ``tzfile`` directly if you have a specific timezone
file on disk that you want to read into a Python ``tzinfo`` object.
If you want to get a ``tzfile`` representing a specific IANA zone,
(e.g. ``'America/New_York'``), you should call
:func:`dateutil.tz.gettz` with the zone identifier.
**Examples:**
Using the US Eastern time zone as an example, we can see that a ``tzfile``
provides time zone information for the standard Daylight Saving offsets:
.. testsetup:: tzfile
from dateutil.tz import gettz
from datetime import datetime
.. doctest:: tzfile
>>> NYC = gettz('America/New_York')
>>> NYC
tzfile('/usr/share/zoneinfo/America/New_York')
>>> print(datetime(2016, 1, 3, tzinfo=NYC)) # EST
2016-01-03 00:00:00-05:00
>>> print(datetime(2016, 7, 7, tzinfo=NYC)) # EDT
2016-07-07 00:00:00-04:00
The ``tzfile`` structure contains a fully history of the time zone,
so historical dates will also have the right offsets. For example, before
the adoption of the UTC standards, New York used local solar mean time:
.. doctest:: tzfile
>>> print(datetime(1901, 4, 12, tzinfo=NYC)) # LMT
1901-04-12 00:00:00-04:56
And during World War II, New York was on "Eastern War Time", which was a
state of permanent daylight saving time:
.. doctest:: tzfile
>>> print(datetime(1944, 2, 7, tzinfo=NYC)) # EWT
1944-02-07 00:00:00-04:00

The ``tzrange`` object is a time zone specified by a set of offsets and
abbreviations, equivalent to the way the ``TZ`` variable can be specified
in POSIX-like systems, but using Python delta objects to specify DST
start, end and offsets.
:param stdabbr:
The abbreviation for standard time (e.g. ``'EST'``).
:param stdoffset:
An integer or :class:`datetime.timedelta` object or equivalent
specifying the base offset from UTC.
If unspecified, +00:00 is used.
:param dstabbr:
The abbreviation for DST / "Summer" time (e.g. ``'EDT'``).
If specified, with no other DST information, DST is assumed to occur
and the default behavior or ``dstoffset``, ``start`` and ``end`` is
used. If unspecified and no other DST information is specified, it
is assumed that this zone has no DST.
If this is unspecified and other DST information is *is* specified,
DST occurs in the zone but the time zone abbreviation is left
unchanged.
:param dstoffset:
A an integer or :class:`datetime.timedelta` object or equivalent
specifying the UTC offset during DST. If unspecified and any other DST
information is specified, it is assumed to be the STD offset +1 hour.
:param start:
A :class:`relativedelta.relativedelta` object or equivalent specifying
the time and time of year that daylight savings time starts. To
specify, for example, that DST starts at 2AM on the 2nd Sunday in
March, pass:
``relativedelta(hours=2, month=3, day=1, weekday=SU(+2))``
If unspecified and any other DST information is specified, the default
value is 2 AM on the first Sunday in April.
:param end:
A :class:`relativedelta.relativedelta` object or equivalent
representing the time and time of year that daylight savings time
ends, with the same specification method as in ``start``. One note is
that this should point to the first time in the *standard* zone, so if
a transition occurs at 2AM in the DST zone and the clocks are set back
1 hour to 1AM, set the ``hours`` parameter to +1.
**Examples:**
.. testsetup:: tzrange
from dateutil.tz import tzrange, tzstr
.. doctest:: tzrange
>>> tzstr('EST5EDT') == tzrange("EST", -18000, "EDT")
True
>>> from dateutil.relativedelta import *
>>> range1 = tzrange("EST", -18000, "EDT")
>>> range2 = tzrange("EST", -18000, "EDT", -14400,
... relativedelta(hours=+2, month=4, day=1,
... weekday=SU(+1)),
... relativedelta(hours=+1, month=10, day=31,

For a given year, get the DST on and off transition times, expressed
always on the standard time side. For zones with no transitions, this
function returns ``None``.
:param year:
The year whose transitions you would like to query.
:return:
Returns a :class:`tuple` of :class:`datetime.datetime` objects,
``(dston, dstoff)`` for zones with an annual DST transition, or
``None`` for fixed offset zones.

tzstra
``tzstr`` objects are time zone objects specified by a time-zone string as
it would be passed to a ``TZ`` variable on POSIX-style systems (see
the `GNU C Library: TZ Variable`_ for more details).
There is one notable exception, which is that POSIX-style time zones use an
inverted offset format, so normally ``GMT+3`` would be parsed as an offset
3 hours *behind* GMT. The ``tzstr`` time zone object will parse this as an
offset 3 hours *ahead* of GMT. If you would like to maintain the POSIX
behavior, pass a ``True`` value to ``posix_offset``.
The :class:`tzrange` object provides the same functionality, but is
specified using :class:`relativedelta.relativedelta` objects. rather than
strings.
:param s:
A time zone string in ``TZ`` variable format. This can be a
:class:`bytes` (2.x: :class:`str`), :class:`str` (2.x:
:class:`unicode`) or a stream emitting unicode characters
(e.g. :class:`StringIO`).
:param posix_offset:
Optional. If set to ``True``, interpret strings such as ``GMT+3`` or
``UTC+3`` as being 3 hours *behind* UTC rather than ahead, per the
POSIX standard.
.. caution::
Prior to version 2.7.0, this function also supported time zones
in the format:
* ``EST5EDT,4,0,6,7200,10,0,26,7200,3600``
* ``EST5EDT,4,1,0,7200,10,-1,0,7200,3600``
This format is non-standard and has been deprecated; this function
will raise a :class:`DeprecatedTZFormatWarning` until
support is removed in a future version.

Retrieve a :py:class:`datetime.tzinfo` object by its ``tzid``.
:param tzid:
If there is exactly one time zone available, omitting ``tzid``
or passing :py:const:`None` value returns it. Otherwise a valid
key (which can be retrieved from :func:`keys`) is required.
:raises ValueError:
Raised if ``tzid`` is not specified but there are either more
or fewer than 1 zone defined.
:returns:
Returns either a :py:class:`datetime.tzinfo` object representing
the relevant time zone or :py:const:`None` if the ``tzid`` was
not found.

Retrieve a time zone object from a string representation
This function is intended to retrieve the :py:class:`tzinfo` subclass
that best represents the time zone that would be used if a POSIX
`TZ variable`_ were set to the same value.
If no argument or an empty string is passed to ``gettz``, local time
is returned:
.. code-block:: python3
>>> gettz()
tzfile('/etc/localtime')
This function is also the preferred way to map IANA tz database keys
to :class:`tzfile` objects:
.. code-block:: python3
>>> gettz('Pacific/Kiritimati')
tzfile('/usr/share/zoneinfo/Pacific/Kiritimati')
On Windows, the standard is extended to include the Windows-specific
zone names provided by the operating system:
.. code-block:: python3
>>> gettz('Egypt Standard Time')
tzwin('Egypt Standard Time')
Passing a GNU ``TZ`` style string time zone specification returns a
:class:`tzstr` object:
.. code-block:: python3
>>> gettz('AEST-10AEDT-11,M10.1.0/2,M4.1.0/3')
tzstr('AEST-10AEDT-11,M10.1.0/2,M4.1.0/3')
:param name:
A time zone name (IANA, or, on Windows, Windows keys), location of
a ``tzfile(5)`` zoneinfo file or ``TZ`` variable style time zone
specifier. An empty string, no argument or ``None`` is interpreted
as local time.
:return:
Returns an instance of one of ``dateutil``'s :py:class:`tzinfo`
subclasses.
.. versionchanged:: 2.7.0
After version 2.7.0, any two calls to ``gettz`` using the same
input strings will return the same object:
.. code-block:: python3
>>> tz.gettz('America/Chicago') is tz.gettz('America/Chicago')
True
In addition to improving performance, this ensures that
`"same zone" semantics`_ are used for datetimes in the same zone.

Given a datetime and a time zone, determine whether or not a given datetime
would fall in a gap.
:param dt:
A :class:`datetime.datetime` (whose time zone will be ignored if ``tz``
is provided.)
:param tz:
A :class:`datetime.tzinfo` with support for the ``fold`` attribute. If
``None`` or not provided, the datetime's own time zone will be used.
:return:
Returns a boolean value whether or not the "wall time" exists in
``tz``.

As a note, :func:`datetime.astimezone` is guaranteed to produce a valid,
existing datetime, so a round-trip to and from UTC is sufficient to get
an extant datetime, however, this generally "falls back" to an earlier time
rather than falling forward to the STD side (though no guarantees are made
about this behavior).
:param dt:
A :class:`datetime.datetime` which may or may not exist.
:return:
Returns an existing :class:`datetime.datetime`. If ``dt`` was not
imaginary, the datetime returned is guaranteed to be the same object
passed to the function.
