Because Windows does not have an equivalent of :func:`time.tzset`, on Windows, :class:`dateutil.tz.tzlocal` instances will always reflect the time zone settings *at the time that the process was started*, meaning changes to the machine's time zone settings during the run of a program on Windows will **not** be reflected by :class:`dateutil.tz.tzlocal`. Because ``tzwinlocal`` reads the registry directly, it is unaffected by this issue. c Csntdtj}t|t}t|}W5QRX|d|_|d|_zBtdj t |jd}t||}t|}|d|_ W5QRXWnt k rd|_ YnXW5QRX|d |d}||d}t j|d |_t j|d |_td |d } | d d \|_|_|_|_| d|_td |d} | d d \|_|_|_|_| d|_|j|j|_||_dS)NZ StandardNameZ DaylightNamez {kn}\{sn})r^Zsnr`ZBiasZ StandardBiasZ DaylightBiasrbz=8hZ StandardStartrr Z DaylightStart) rr r rTZLOCALKEYNAMErjrCrDrrirrQOSErrorrmrnr9r:rkrlrVr=r?rAr;rUr>r@rBr<r[rZrS) r rZ tzlocalkeyrprorKZ_keydictrrrsrqrrrr!sD        ztzwinlocal.__init__cCsdS)Nz tzwinlocal()rr6rrrruBsztzwinlocal.__repr__cCsdt|jS)Nztzwinlocal(%s))rtrCr6rrr__str__Esztzwinlocal.__str__cCs |jdfS)Nr)rvr6rrrrwIsztzwinlocal.__reduce__N)r/r0r1r2r!rur{rwrrrrrs .c CsTt||d||}|j||ddd}||dt}|j|krP|t8}|S)z> dayofweek == 0 means Sunday, whichweek 5 means last instance rr )day)rmreplace isoweekdayONEWEEKmonth) rXrZ dayofweekhourminuteZ whichweekfirstZ weekdayonewdrrrrTMs  rTcCsi}t|d}d}t|D]v}t||\}}}|tjksH|tjkrZ|d@r|d}n2|tjkr|dr|pvt}| |}| d}|||<q|S)z0Convert a registry key's values to a dictionary.rNllz@tzres) rrNrMZ EnumValueZ REG_DWORDZREG_DWORD_LITTLE_ENDIANREG_SZr*r r.rstrip)keyZdoutsizeZtz_resrIZkey_namevalueZdtyperrrrj[s        rj)r2rmrkZ six.movesrsixrrrr- ImportErrorZ_commonr__all__rnrrrryrrobjectr r4rrrTrjrrrrs.
