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 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 c Csddlma||_||_yt|}Wnttfk rKnXyt|}Wnttfk runX|dk rtj d||_ n t |_ |dk rtj d||_ n;|r|dk r|j tj dd |_ n t |_ |rI|dkrItjdd ddd dd tj d |_n ||_|r|dkrtjdd dd d d d tj d|_n ||_|j |j |_t|j|_dS( Ni(t relativedeltaR$thoursiitmonthitdaytweekdayi i(tdateutilRt _std_abbrt _dst_abbrRR&R'R R(R)R3R R6tSUt _start_deltat _end_deltat_dst_base_offset_R8thasdst(R tstdabbrt stdoffsettdstabbrRMtstarttend((s7/tmp/pip-build-wDUJoH/python-dateutil/dateutil/tz/tz.pyR,Js:        ,  + cCsF|js dStj|dd}||j}||j}||fS(s For a given year, get the DST on and off transition times, expressed always on the standard time side.
