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 Csntjdtj}tj|t}t|}WdQRX|d|_|d|_yBtdj t |jd}tj||}t|}|d|_ WdQRXWnt k rd|_ YnXWdQRX|d |d}||d}t j|d |_t j|d |_tjd |d } | d d \|_|_|_|_| d|_tjd |d} | d d \|_|_|_|_| d|_|j|j|_|j|_dS)NZ StandardNameZ DaylightNamez {kn}\{sn})r[Zsnr]ZBiasZ StandardBiasZ DaylightBias)r_z=8hZ StandardStartrr Z DaylightStart) rr r r TZLOCALKEYNAMErfrArBrrerrNOSErrorrirjr7r8rgrhrSr;r=r?r9rRr<r>r@r:rXrWrP) rrZ tzlocalkeyrlrkrHZ_keydictrnrormrrrr s2       ztzwinlocal.__init__cCsdS)Nz tzwinlocal()r)rrrrrqBsztzwinlocal.__repr__cCsdt|jS)Nztzwinlocal(%s))rprA)rrrr__str__Esztzwinlocal.__str__cCs |jffS)N)rr)rrrrrsIsztzwinlocal.__reduce__N)r.r/r0r1r rqrwrsrrrrrs .c CsTtj||d||}|j||jddd}||dt}|j|krP|t8}|S)z> dayofweek == 0 means Sunday, whichweek 5 means last instance rr )day)rireplace isoweekdayONEWEEKmonth) rUr|Z dayofweekhourminuteZ whichweekfirstZ weekdayonewdrrrrQMs  rQcCsi}tj|d}d}xt|D]v}tj||\}}}|tjksJ|tjkr\|d@r|d}n2|tjkr|jdr|pxt}|j |}|j d}|||<q W|S) z0Convert a registry key's values to a dictionary.rN z@tzresll) rrKrJ EnumValueZ REG_DWORDZREG_DWORD_LITTLE_ENDIANREG_SZr)r r-rstrip)keyZdoutsizeZtz_resrGZkey_namevalueZdtyperrrrf[s       rf)r1rirgZ six.movesrsixrrrr, ImportErrorZ_commonr__all__rjr{rrrurrobjectr r3rrrQrfrrrrs.
