class tzrangebase(_tzinfo): (source)

Known subclasses: dateutil.tz.tz.tzrange, dateutil.tz.win.tzwinbase

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. .. versionadded:: 2.6.0

Inherited from _tzinfo:

Method	`_fold`	Undocumented
Method	`_fold_status`	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``.
Method	`_fromutc`	Given a timezone-aware datetime in a given timezone, calculates a timezone-aware datetime in a new timezone.
