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. .. __: http://docs.python.org/library/datetime.html#datetime-tzinfo cCs@|dk r$tjd|ƒ|_n|dk r<||_ndS(Ntminutes(tNonetdatetimet timedeltat_offsett_name(tselftoffsettname((s>/opt/alt/python27/lib64/python2.7/site-packages/psycopg2/tz.pyt__init__5s  cCs_||f}y|j|SWn=tk rZtt|ƒj|||ƒ}||j|<|SXdS(s@Return a suitable instance created earlier if it exists N(t_cachetKeyErrortsuperRt__new__(tclsRR tkeyttz((s>/opt/alt/python27/lib64/python2.7/site-packages/psycopg2/tz.pyR;s   cCs3|jjd|jjdd}d||jfS(Ni<is3psycopg2.tz.FixedOffsetTimezone(offset=%r, name=%r)(RtsecondstdaysR(Rt offset_mins((s>/opt/alt/python27/lib64/python2.7/site-packages/psycopg2/tz.pyt__repr__Fs"cCs/|jjd|jjdd}||jfS(Ni<i(RRRR(RR((s>/opt/alt/python27/lib64/python2.7/site-packages/psycopg2/tz.pyt__getinitargs__Ks"cCs|jS(N(R(Rtdt((s>/opt/alt/python27/lib64/python2.7/site-packages/psycopg2/tz.pyt utcoffsetOscCso|jdk r|jS|jj|jjd}t|dƒ\}}|d}|rcd||fSd|SdS(Ni€Qii<s%+03d:%ds%+03d(RRRRRtdivmod(RRRthoursR((s>/opt/alt/python27/lib64/python2.7/site-packages/psycopg2/tz.pyttznameRs cCstS(N(tZERO(RR((s>/opt/alt/python27/lib64/python2.7/site-packages/psycopg2/tz.pytdst^sN(t__name__t __module__t__doc__RRRRR R RRRRRR(((s>/opt/alt/python27/lib64/python2.7/site-packages/psycopg2/tz.pyR"s     Rt LocalTimezonecBs2eZdZd„Zd„Zd„Zd„ZRS(snPlatform idea of local timezone.
