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 NcCs8|dk r&t|tjs tj|d}||_|dk r4||_dS)N)minutes) isinstancedatetime timedelta_offset_name)selfoffsetnamer LC:\Users\vtejo\AppData\Local\Temp\pip-unpacked-wheel-8c51wohf\psycopg2\tz.py__init__<s   zFixedOffsetTimezone.__init__csL||f}z |j|WStk rFt|||}||j|<|YSXdS)z@Return a suitable instance created earlier if it exists N)_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|jkStSdSNrrrNotImplementedr otherr r r __eq__Ss  zFixedOffsetTimezone.__eq__cCst|tr|j|jkStSdSrrrr r r __ne__Ys  zFixedOffsetTimezone.__ne__cCs |j|jfSrrrr r r __getinitargs___sz#FixedOffsetTimezone.__getinitargs__cCs|jSr)rr dtr r r utcoffsetbszFixedOffsetTimezone.utcoffsetcCsb|jdk r|jSt|jd\}}t|d\}}d|}|sB|r^|d|7}|r^|d|7}|S)N<z%+03dz:%02d)rdivmodr total_seconds)r r$rsecondshoursrvr r r tznamees   zFixedOffsetTimezone.tznamecCstSr)ZEROr#r r r dstsszFixedOffsetTimezone.dst)NN)NN)__name__ __module__ __qualname____doc__rr-rrrrrr r!r"r%r,r. __classcell__r r rr r$s  r)r)c@s0eZdZdZddZddZddZdd Zd S) LocalTimezoneznPlatform idea of local timezone.
