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 Cstdtj}t|t}t|}Wdn1s:0Y|d|_|d|_zVtdj t |jd}t||"}t|}|d|_ Wdn1s0YWnt yd|_ Yn0Wdn1s0Y|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})rcsnreBiasZ StandardBiasZ DaylightBiasrgz=8hZ StandardStartrr Z DaylightStart) rr r rTZLOCALKEYNAMErorFrGrrnrrTOSErrorrrrsr<r=rprqrYr@rBrDr>rXrArCrEr?r`r_rV) r#rZ tzlocalkeyrurtrNZ_keydictrwrxrvrrrr$sD&   , *     ztzwinlocal.__init__cCsdS)Nz tzwinlocal()rr9rrrrzBsztzwinlocal.__repr__cCsdt|jS)Nztzwinlocal(%s))ryrFr9rrr__str__Esztzwinlocal.__str__cCs |jdfS)Nr)r{r9rrrr|Isztzwinlocal.__reduce__N)r2r3r4r5r$rzrr|rrrrrs .rc CsTt||d||}|j||ddd}||dt}|j|krP|t8}|S)z> dayofweek == 0 means Sunday, whichweek 5 means last instance rr )day)rrreplace isoweekdayONEWEEKmonth) r[r dayofweekhourminuteZ whichweekfirstZ weekdayonewdrrrrWMs  rWcCsi}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) rrQrP EnumValueZ REG_DWORDZREG_DWORD_LITTLE_ENDIANREG_SZr-r r1rstrip)keydoutsizeZtz_resrLkey_namevaluedtyperrrro[s        ro)r5rrrp six.movesrsixrrrr0 ImportError_commonr__all__rsrrrrrrobjectr r7rrrWrorrrrs.
