: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 Ncstt|d}t|tr2||_t|d}d}n.|durB||_nt|drV|j|_n t ||_|dur|stt |}|}| |}Wdn1s0Y| |dS)NFrbTr?) rFr~rAr!r _filenameopenhasattrr?rC _nullcontext _read_tzfile _set_tzdata)rfileobjfilenameZfile_opened_hereZ file_streamtzobjrRrrrAs"     (ztzfile.__init__cCs&tjD]}t|d|t||qdS)z= Set the time zone data of this object from a _tzfile object _N)rrr{rgrZ)rrrhrrrrs ztzfile._set_tzdatac st|ddkr td|dtd|d\}}}}}}|rnttd|||d_ng_|rtd|||_ng_g}t |D]} | td |d q||} |r| |d t j |rtd |||} |rtd |||} g_t |D]} || \} }}t| } t}| |_td |_tj| d|_||_| || d||_|| ko| | d k|_|| ko| | d k|_j |q,fddjD_d_d_d_jrjsjd __nt |dddD]T} j| }jsJ|jsJ|_njs`|jr`|_jr$jr$qq$jrjsj_jD]}|js|_qqjd _d}d}d}d}g_t jD]\} }|j}d }|dur4|jr4|s||}|s"|r"|}tj|d|_|}||}|}|durd||krd|j|krd|}|j}|}|}j j| |qt!j_t!j_t!j_S)NZTZifzmagic not foundz>6lz>%dlz>%dBz>lbbz>%dbrr6csg|]}j|qSr)rv).0idxoutrr sz'tzfile._read_tzfile..r)"rrreaddecode ValueErrorstructunpacklistrtrurangerjseekosSEEK_CURrvr>r^r@r<r=rdr_r`findrarbrcrwrxryrzrs enumeraterP)rrZ ttisgmtcntZ ttisstdcntZleapcntZtimecntZtypecntZcharcntZttinfoirarbrcZgmtoffr`ZabbrindttiZlastdstZ lastoffsetZ lastdstoffsetZlastbaseoffsetr@rdZ baseoffsetZ adjustmentrrrrs                          ztzfile._read_tzfileFcCs6|js dSt|}|r|jn|j}t||}|dS)Nr) _trans_listrUZ_trans_list_utcbisectZ bisect_right)rrin_utcrXrsrrrr_find_last_transitions  ztzfile._find_last_transitioncCs8|dus|dt|jkr |jS|dkr.|jS|j|S)Nrr)lenr _ttinfo_stdZ_ttinfo_before _trans_idx)rrrrr _get_ttinfos ztzfile._get_ttinfocCs||}||Sr)_resolve_ambiguous_timer)rrrrrr _find_ttinfos ztzfile._find_ttinfocCsnt|tjstd|j|ur&td|j|dd}||}|tj|jd}|j ||d}t |t |dS)a The ``tzfile`` implementation of :py:func:`datetime.tzinfo.fromutc`. :param dt: A :py:class:`datetime.datetime` object. :raises TypeError: Raised if ``dt`` is not a :py:class:`datetime.datetime` object. :raises ValueError: Raised if this is called with a ``dt`` which does not have this ``tzinfo`` attached. :return: Returns a :py:class:`datetime.datetime` object representing the wall time in ``self``'s time zone. z&fromutc() requires a datetime argumentzdt.tzinfo is not selfT)rr6)rrY) r!r<r:tzinforrrr=r@rr rD)rrrrZdt_outrYrrrr s   ztzfile.fromutccCsd|dur||}t|}||}|dus4|dkr8dS||dj|j}|j|}|||kS)rNrFr)rrUrr@r)rrrrXrZodttrrrr s   ztzfile.is_ambiguouscCsF||}||}|dus$|dkr(|St| o:|||}||S)Nr)rr[rDr)rrrr[Z idx_offsetrrrr(s   ztzfile._resolve_ambiguous_timecCs"|dur dS|jstS||jSr)rrrr_rrrrr5s ztzfile.utcoffsetcCs0|dur dS|jstS||}|js*tS|jSr)Z _ttinfo_dstrrr`rd)rrrrrrr>s z tzfile.dstcCs|jr|durdS||jSr)rrrarrrrrNsz tzfile.tznamecCs2t|tstS|j|jko0|j|jko0|j|jkSr)r!r~r#rrZ _ttinfo_listr%rrrr'Ts    z tzfile.__eq__cCs ||k Srrr%rrrr(]sz tzfile.__ne__cCsd|jjt|jfSNri)r+r,rCrr-rrrr.`sztzfile.__repr__cCs |dSr) __reduce_ex__r-rrrr4csztzfile.__reduce__cCs|jd|jf|jfSr)r+r__dict__)rZprotocolrrrrfsztzfile.__reduce_ex__)N)F)N)r,r/r0r1rArrrrrr rrrrrrr'r2r(r.r4rr]rrrRrr~s*Ga  $    r~c@s6eZdZdZd ddZddZddZed d ZdS) tzrangea[ 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, ... weekday=SU(-1))) >>> tzstr('EST5EDT') == range1 == range2 True Nc Cs<ddlma||_||_z |}Wnttfy:Yn0z |}Wnttfy^Yn0|durxtj|d|_ nt |_ |durtj|d|_ n(|r|dur|j tjdd|_ nt |_ |r|durtjdddt dd|_ n||_ |r|durtjdd d t d d|_n||_|j |j |_t|j |_dS) Nr relativedeltar6rhoursr)rmonthdayweekday r)dateutilr _std_abbr _dst_abbrr9r:r;r<r=rIrrLSU _start_delta _end_delta_dst_base_offset_rNhasdst)rstdabbr stdoffsetdstabbrrdstartendrrrrAs>       ztzrange.__init__cCs4|js dSt|dd}||j}||j}||fS)a For a given year, get the DST on and off transition times, expressed always on the standard time side.

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. .. _`GNU C Library: TZ Variable`: https://www.gnu.org/software/libc/manual/html_node/TZ-Variable.html Fc Csddlma||_t|}|dus*|jr2td|jdvrN|sN|jd9_t j ||j|j|j |j ddd|j sd|_ d|_n&||j|_ |j r|j|jdd |_t|j |_dS) Nr)_parserzunknown string formatr\rrF)rrr)isend)Zdateutil.parserrparser_sZ_parsetzZany_unused_tokensrrrrrArrdrr_deltarrrNr)rsZ posix_offsetresrrrrA7s$  ztzstr.__init__rcCs>ddlm}i}|jdurr|j|d<|jdur`||j|j|d<|jdkrVd|d<qpd|d<q|jr|j|d<n*|jdur|j|d<n|jdur|j|d <|s|sd |d<d|d<|d|d<nd |d<d|d<|d |d<|j dur|j |d <nd|d <|r.|j |j }|d |j |j d8<|jfi|S)NrrrrrrrZyeardayZ nlyeardayrrrr7i iQ)rrrrZweekrZydayZjydayrrGrLrIr7Zdays)rxrrr}r_rrrrWs<               z tzstr._deltacCsd|jjt|jfSrr+r,rCrr-rrrr.sztzstr.__repr__N)F)r)r,r/r0r1rArr.rrrrr s) )rc@seZdZdddZdS)_tzicalvtzcompNcCs@tj|d|_tj|d|_|j|j|_||_||_||_dSr5)r<r= tzoffsetfrom tzoffsetto tzoffsetdiffr`rrrule)rrrr`rrrrrrAs z_tzicalvtzcomp.__init__)NN)r,r/r0rArrrrrsrcsZeZdZgffdd ZddZddZddZd d Zed d Z d dZ e j Z Z S) _tzicalvtzcs4tt|||_||_g|_g|_t|_ dSr) rFrrA_tzid_comps _cachedate _cachecompr allocate_lock _cache_lock)rtzidcompsrRrrrAs z_tzicalvtz.__init__cCsTt|jdkr|jdS|jdd}zH|j.|j|j|||fWdWS1s`0YWnty~Yn0d}d}|jD](}| ||}|r|r||kr|}|}q|s|jD]}|j s|}qq|d}|jZ|j d|||f|j d|t|jdkr0|j |j Wdn1sF0Y|S)Nrrrr) rrreplacerrrindexr[r _find_compdtr`insertpop)rrZ lastcompdtZlastcompcompcompdtrrr _find_comps<    *     *z_tzicalvtz._find_compcCs2|jtkr||r||j8}|jj|dd}|S)NT)Zinc)rrr[rbefore)rrrrrrrrs z_tzicalvtz._find_compdtcCs|dur dS||jSr)rrrrrrrsz_tzicalvtz.utcoffsetcCs||}|jr|jStSdSr)rr`rr)rrrrrrrs z_tzicalvtz.dstcCs ||jSr)rrrrrrrsz_tzicalvtz.tznamecCsdt|jS)Nz)rCrr-rrrr.sz_tzicalvtz.__repr__)r,r/r0rArrrrrrr.r3r4r]rrrRrrs - rc@sBeZdZdZddZddZdddZd d Zd d Zd dZ dS)tzicala[ This object is designed to parse an iCalendar-style ``VTIMEZONE`` structure as set out in `RFC 5545`_ Section 4.6.5 into one or more `tzinfo` objects. :param `fileobj`: A file or stream in iCalendar format, which should be UTF-8 encoded with CRLF endings. .. _`RFC 5545`: https://tools.ietf.org/html/rfc5545 cCs~ddlmat|tr(||_t|d}nt|dt||_t|}i|_ |}| | Wdn1sp0YdS)Nr)rrr?) rrr!rrrrZrCr_vtz _parse_rfcr)rrZfobjrrrrAs   ztzical.__init__cCst|jS)z?

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.
