The last (additional) element is the time zone offset in seconds, except if the timezone was specified as -0000. In that case the last element is None. This indicates a UTC timestamp that explicitly declaims knowledge of the source timezone, as opposed to a +0000 timestamp that indicates the source timezone really was UTC.

If self is not looking at an instance of `beginchar' then getdelimited returns the empty string. `endchars' is a sequence of allowable end-delimiting characters. Parsing stops when one of these is encountered. If `allowcomments' is non-zero, embedded RFC 2822 comments are allowed within the parsed fragment. r FrA r� rs T)r ry rU rW r� r� r� )r� � beginchar�endchars� allowcomments�slistr r> r> r? � getdelimited� s( zAddrlistClass.getdelimitedc C s | j ddd�S )z1Get a quote-delimited fragment from self's field.rt z" F)r� )r� r> r> r? r� � s zAddrlistClass.getquotec C s | j ddd�S )z7Get a parenthesis-delimited fragment from self's field.r� z) T)r� )r� r> r> r? r� � s zAddrlistClass.getcommentc C s d| j ddd� S )z!Parse an RFC 2822 domain-literal.z[%s]r� z] F)r� )r� r> r> r? r� � s z AddrlistClass.getdomainliteralNc C sh dg}|dkr| j }xH| jt| j�k r\| j| j |kr:P n|j| j| j � | jd7 _qW tj|�S )a Parse an RFC 2822 atom.
