|
Provides a unified interface for assigning the ``fold`` attribute to
|
datetimes both before and after the implementation of PEP-495.
|
|
:param fold:
|
The value for the ``fold`` attribute in the returned datetime. This
|
should be either 0 or 1.
|
|
:return:
|
Returns an object for which ``getattr(dt, 'fold', 0)`` returns
|
``fold`` for all versions of Python. In versions prior to
|
Python 3.6, this is a ``_DatetimeWithFold`` object, which is a
|
subclass of :py:class:`datetime.datetime` with the ``fold``
|
attribute added, if ``fold`` is 1.

This is a class designed to provide a PEP 495-compliant interface for

Python versions before 3.6. It is used only for dates in a fold, so

the ``fold`` attribute is fixed at ``1``.

|
Return a datetime with the same attributes, except for those
|
attributes given new values by whichever keyword arguments are
|
specified. Note that tzinfo=None can be specified to create a naive
|
datetime from an aware datetime with no conversion of date and time
|
data.
|
|
This is reimplemented in ``_DatetimeWithFold`` because pypy3 will
|
return a ``datetime.datetime`` even if ``fold`` is unchanged.

Determine the fold status of a "wall" datetime, given a representation
|
of the same datetime as a (naive) UTC datetime. This is calculated based
|
on the assumption that ``dt.utcoffset() - dt.dst()`` is constant for all
|
datetimes, and that this offset is the actual number of hours separating
|
``dt_utc`` and ``dt_wall``.
|
|
:param dt_utc:
|
Representation of the datetime as UTC
|
|
:param dt_wall:
|
Representation of the datetime as "wall time". This parameter must
|
either have a `fold` attribute or have a fold-naive
|
:class:`datetime.tzinfo` attached, otherwise the calculation may
|
fail.

Given a timezone-aware datetime in a given timezone, calculates a
|
timezone-aware datetime in a new timezone.
|
|
Since this is the one time that we *know* we have an unambiguous
|
datetime object, we take this opportunity to determine whether the
|
datetime is ambiguous and in a "fold" state (e.g. if it's the first
|
occurrence, chronologically, of the ambiguous datetime).
|
|
:param dt:
|
A timezone-aware :class:`datetime.datetime` object.

|
This is an abstract base class for time zones represented by an annual
|
transition into and out of DST. Child classes should implement the following
|
methods:
|
|
* ``__init__(self, *args, **kwargs)``
|
* ``transitions(self, year)`` - this is expected to return a tuple of
|
datetimes representing the DST on and off transitions in standard
|
time.
|
|
A fully initialized ``tzrangebase`` subclass should also provide the
|
following attributes:
|
* ``hasdst``: Boolean whether or not the zone uses DST.
|
* ``_dst_offset`` / ``_std_offset``: :class:`datetime.timedelta` objects
|
representing the respective UTC offsets.
|
* ``_dst_abbr`` / ``_std_abbr``: Strings representing the timezone short
|
abbreviations in DST and STD, respectively.
|
* ``_hasdst``: Whether or not the zone has DST.
