If omitted and ``fileobj`` is a file stream, this parameter will be set either to ``fileobj``'s ``name`` attribute or to ``repr(fileobj)``. This class is intended to be mostly equivalent to the standard library :py:class:`zoneinfo.ZoneInfo` class. The primary differences are: * All caching in ``tzfile`` is handled by :func:`tz.gettz` level (you should generally not attempt to construct a ``tzfile`` directly). * ``tzfile`` objects are pickled by value rather than by reference to the IANA key. * ``tzfile`` has equality-by-value semantics, whereas :py:class:`~zoneinfo.ZoneInfo` has equality-by-identity semantics. 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. .. versionchanged:: 3.0.0 ``tzfile`` is now a partial backport of :py:class:`zoneinfo.ZoneInfo`, which brings with it support for Version 2 and 3 ``tzfile(5)`` binaries. **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 standard time on November 18, 1883, New York used local mean time: .. doctest:: tzfile >>> print(datetime(1883, 11, 18, tzinfo=NYC)) # LMT 1883-11-18 00:00:00-04:56:02 Python versions before 3.6 do not support sub-minute offsets, so there the offset is rounded to ``-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 Ncstt|d}t|tjr||_t|d}d}n|dur"||_nt|dr,|j |_n |dur4||_nt ||_|durZ|sCt |}| }| |Wdn1sUwY||_ dS)NFrbTname)superr1__init__ isinstancesix string_typesr)openhasattrr3reprr _load_filer()selffileobjr-r,file_opened_here file_stream __class__r rr5s(       ztzfile.__init__cC|jS)u Read-only attribute returning the ``key`` constructor argument. For zones generated from :func:`gettz`, this will be the IANA key passed to ``gettz`` — no normalization is done, so although in most distributions of the time zone database "US/Eastern" is a link to "America/New_York", ``tz.gettz("US/Eastern").key`` should always return ``"US/Eastern"``.

TZif files give the total UTC offset of each local time type and whether it is DST, but not how much of the offset is DST, so this has to be worked out from the standard time on either side of each DST period. That is done for each transition rather than for each local time type, because zic reuses a local time type for periods with different standard offsets (e.g. UTC+0 DST in the Azores was double summer time in the 1940s and summer time later). css|] \}}|s|VqdSr r )rrOrVr r r Ez+tzfile._utcoff_to_dstoff..NrrXcs4g|]}|r||kr||fqSr r rr)afterbeforerr rrVsz,tzfile._utcoff_to_dstoff..rcSsh|]}|r|qSr r rcr r r asz+tzfile._utcoff_to_dstoff..cSsh|] }|ddkr|qS)i,rr rr r rrfrcs(h|]\}}t|tkr|qSr )abs_DST_CONSENSUS_WINDOW)rrsrU)rrr rrps cSs|dkt|fSNr)r)rr r r}sz*tzfile._utcoff_to_dstoff..r,rw)rnextrrmin)rr utcoffsetsisdstsnfirst_std_utcoffindicesimplied std_utcoffrl clear_cutdstoffs candidates plausiblenearby consensusr )rrrrrr3sP             ztzfile._utcoff_to_dstoffcCs|sgggSt|t|g}t|dkr(|d}||d}||kr'||}}n|d}}|dd|7<|dd|7<tdt|D]-}|||d}|||}||krb||}}|d||7<|d||7<qI|S)zGenerate number of seconds since 1970 *in the local time*.
