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. .. versionchanged:: 2.9 The constructor can take either a timedelta or a number of minutes of offset. Previously only minutes were supported. .. __: https://docs.python.org/library/datetime.html NcCs<|durt|tjstj|d}||_|dur||_dSdS)N)minutes) isinstancedatetime timedelta_offset_name)selfoffsetnamer -/usr/lib/python3/dist-packages/psycopg2/tz.py__init__<s   zFixedOffsetTimezone.__init__csF||f}z|j|WSty"t|||}||j|<|YSw)z@Return a suitable instance created earlier if it exists )_cacheKeyErrorsuper__new__)clsr r keytz __class__r r rDs   zFixedOffsetTimezone.__new__cCsd|j|jfS)Nz3psycopg2.tz.FixedOffsetTimezone(offset=%r, name=%r)rrr r r r __repr__Os zFixedOffsetTimezone.__repr__cCst|tr |j|jkStSNrrrNotImplementedr otherr r r __eq__S  zFixedOffsetTimezone.__eq__cCst|tr |j|jkStSrrrr r r __ne__Yr!zFixedOffsetTimezone.__ne__cCs |j|jfSrrrr r r __getinitargs___s z#FixedOffsetTimezone.__getinitargs__cCs|jSr)rr dtr r r utcoffsetbszFixedOffsetTimezone.utcoffsetcCsb|jdur|jSt|jd\}}t|d\}}d|}|s!|r/|d|7}|r/|d|7}|S)N<z%+03dz:%02d)rdivmodr total_seconds)r r%rsecondshoursrvr r r tznamees   zFixedOffsetTimezone.tznamecCstSr)ZEROr$r r r dstsszFixedOffsetTimezone.dst)NN)__name__ __module__ __qualname____doc__rr.rrrrrr r"r#r&r-r/ __classcell__r r rr r$s  r)r*c@s0eZdZdZddZddZddZdd Zd S) LocalTimezoneznPlatform idea of local timezone.
