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 NcCs@ddlma||_||_yt|�}Wnttfk r<YnXyt|�}Wnttfk rbYnX|dk r|tj|d�|_ nt |_ |dk r�tj|d�|_n(|r�|dk r�|j tjdd�|_nt |_|r�|dkr�tjdddtjd �d�|_ n||_ |�r|dk�rtjdd d tjd�d�|_n||_|j|j |_t|j �|_dS)Nr)� relativedelta)r(r)�hours�rn)r��month�day�weekday� �rr�rrrz)�dateutilr�� _std_abbr� _dst_abbrrr*r+r,r-r7r r8�SU�_start_delta� _end_delta�_dst_base_offset_r:�hasdst)r�stdabbr� stdoffset�dstabbrrK�start�endrrrr0Js:ztzrange.__init__cCs4|js dStj|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. .. _`GNU C Library: TZ Variable`: https://www.gnu.org/software/libc/manual/html_node/TZ-Variable.html Fc Cs�ddlma||_tj|�}|dkr,td��|jd krJ|rJ|jd9_tj||j|j|j |j ddd�|j s~d|_d|_n&|j |j�|_|jr�|j |jdd �|_t|j�|_dS)Nr)�parserzunknown string format�GMTrrF)r�r�)�isend)r�rrz)r�r��_sZ_parsetzr}r�r�r�r0r�rKr�r��_deltar�r�r:r�)r�sZposix_offset�resrrrr0�s" ztzstr.__init__rcCs<ddlm}i}|jdk rr|j|d<|jdk r`|j|j|j�|d<|jdkrVd|d<qpd|d<q�|jr�|j|d<n*|jdk r�|j|d<n|jdk r�|j|d <|s�|s�d |d<d|d<|jd�|d<nd|d<d|d<|jd�|d<|j dk �r�|j |d<nd |d<|�r0|j |j}|d|j|j d8<|jf|�S)Nr)r�r�r�rr�r�ZyeardayZ nlyeardayrnr�r(i i�Qrrz)r�r�r�r�Zweekr�ZydayZjydayr�r5r8r7r(Zdays)r�xr�r�rarFrrrr��s< ztzstr._deltacCsd|jjt|j�fS)Nz%s(%s))rr r1r�)rrrrr!sztzstr.__repr__N)F)r)r r"r#r$r0r�r!rrrrr��s )r�c@seZdZddd�ZdS)�_tzicalvtzcompNcCs@tj|d�|_tj|d�|_|j|j|_||_||_||_dS)N)r()r,r-�tzoffsetfrom� tzoffsetto�tzoffsetdiffrGr�rrule)rr�r�rGrr�rrrr0sz_tzicalvtzcomp.__init__)NN)r r"r#r0rrrrr�sr�csZeZdZgf�fdd� Zdd�Zdd�Zdd�Zd d �Zedd��Z d d�Z ejZ�Z S)� _tzicalvtzcs*tt|�j�||_||_g|_g|_dS)N)r4r�r0�_tzid�_comps� _cachedate� _cachecomp)r�tzid�comps)rrrr0s z_tzicalvtz.__init__c Cs t|j�dkr|jdS|jdd�}y|j|jj||j|�f�Stk rTYnXd}d}x4|jD]*}|j||�}|rf|s�||krf|}|}qfW|s�x"|jD]}|j s�|}Pq�W|d}|jj d||j|�f�|jj d|�t|j�dk�r|jj�|jj�|S)Nrr)r�r�)r�r��replacer�r��indexrCr}�_find_compdtrG�insert�pop)rrZ lastcompdtZlastcomp�comp�compdtrrr� _find_comps4 z_tzicalvtz._find_compcCs2|jtkr|j|�r||j8}|jj|dd�}|S)NT)Zinc)r�r rCr�Zbefore)rr�rr�rrrr�Is z_tzicalvtz._find_compdtcCs|dkrdS|j|�jS)N)r�r�)rrrrrrQsz_tzicalvtz.utcoffsetcCs|j|�}|jr|jStSdS)N)r�rGr�r )rrr�rrrrWs z_tzicalvtz.dstcCs|j|�jS)N)r�r)rrrrrr^sz_tzicalvtz.tznamecCsdt|j�S)Nz)r1r�)rrrrr!bsz_tzicalvtz.__repr__)r r"r#r0r�r�rrrrr!r&r'rDrr)rrr�s*r�c@sBeZdZdZdd�Zdd�Zddd�Zd d �Zdd�Zd d�Z dS)�tzicala\ This object is designed to parse an iCalendar-style ``VTIMEZONE`` structure as set out in `RFC 2445`_ 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 2445`: https://www.ietf.org/rfc/rfc2445.txt c Csjddlmat|t�r(||_t|d�}nt|dt|��|_t|�}i|_ |�}|j |j��WdQRXdS)Nr)r��rr.)r�r�rrr�rerBr1rg�_vtz� _parse_rfcr{)rrjZfobjrrrr0ss ztzical.__init__cCst|jj��S)z?
