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 Nc C s( |d k rt j|d�| _|d k r$|| _d S )N)�minutes)�datetime� timedelta�_offset�_name)�self�offset�name� r �>/opt/alt/python37/lib64/python3.7/site-packages/psycopg2/tz.py�__init__6 s z FixedOffsetTimezone.__init__c sJ ||f}y | j | S tk rD tt| ��| ||�}|| j |< |S X dS )z@Return a suitable instance created earlier if it exists N)�_cache�KeyError�superr �__new__)�clsr r �key�tz)� __class__r r r < s zFixedOffsetTimezone.__new__c C s* | j jd | j jd d }d|| jf S )N�< � z3psycopg2.tz.FixedOffsetTimezone(offset=%r, name=%r))r �seconds�daysr )r � offset_minsr r r �__repr__G s z FixedOffsetTimezone.__repr__c C s& | j jd | j jd d }|| jfS )Nr r )r r r r )r r r r r �__getinitargs__L s z#FixedOffsetTimezone.__getinitargs__c C s | j S )N)r )r �dtr r r � utcoffsetP s z FixedOffsetTimezone.utcoffsetc C sV | j d k r| j S | jj| jjd }t|d�\}}|d }|rJd||f S d| S d S )Ni�Q i r z%+03d:%dz%+03d)r r r r �divmod)r r r �hoursr r r r �tznameS s zFixedOffsetTimezone.tznamec C s t S )N)�ZERO)r r r r r �dst_ s zFixedOffsetTimezone.dst)NN)NN)�__name__� __module__� __qualname__�__doc__r r" r r r r r r r r! r# � __classcell__r r )r r r # s r )r c @ s0 e Zd ZdZdd� Zdd� Zdd� Zdd � Zd S ) � LocalTimezoneznPlatform idea of local timezone.
