This is exactly the implementation__ found in Python 2.3.x documentation, with a small change to the `!__init__()` method to allow for pickling and a default name in the form ``sHH:MM`` (``s`` is the sign.). The implementation also caches instances. During creation, if a FixedOffsetTimezone instance has previously been created with the same offset and name that instance will be returned. This saves memory and improves comparability. .. __: https://docs.python.org/library/datetime.html NcCs(|dk rtj|d|_|dk r$||_dS)N)minutes)datetime timedelta_offset_name)selfoffsetnamer >/opt/alt/python37/lib64/python3.7/site-packages/psycopg2/tz.py__init__6szFixedOffsetTimezone.__init__csJ||f}y |j|Stk rDtt||||}||j|<|SXdS)z@Return a suitable instance created earlier if it exists N)_cacheKeyErrorsuperr__new__)clsr r keyZtz) __class__r r r<s  zFixedOffsetTimezone.__new__cCs*|jjd|jjdd}d||jfS)N<z3psycopg2.tz.FixedOffsetTimezone(offset=%r, name=%r))rsecondsdaysr)r offset_minsr r r __repr__GszFixedOffsetTimezone.__repr__cCs&|jjd|jjdd}||jfS)Nrr)rrrr)rrr r r __getinitargs__Lsz#FixedOffsetTimezone.__getinitargs__cCs|jS)N)r)rdtr r r utcoffsetPszFixedOffsetTimezone.utcoffsetcCsV|jdk r|jS|jj|jjd}t|d\}}|d}|rJd||fSd|SdS)NiQirz%+03d:%dz%+03d)rrrrdivmod)rrrZhoursrr r r tznameSs  zFixedOffsetTimezone.tznamecCstS)N)ZERO)rrr r r dst_szFixedOffsetTimezone.dst)NN)NN)__name__ __module__ __qualname____doc__rr rrr rrrrrr! __classcell__r r )rr r#s    r)rc@s0eZdZdZddZddZddZdd Zd S) LocalTimezoneznPlatform idea of local timezone.
