S ) a Convert date to extended time tuple.
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.

AddrlistClassa Address parser class by Ben Escoto.
To understand what this class does, it helps to have a copy of RFC 2822 in
front of you.
Note: this class interface is deprecated and may be removed in the future.
Use email.utils.AddressList instead.

`beginchar' is the start character for the fragment.
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.

Optional atomends specifies a different set of end token delimiters
(the default is to use self.atomends). This is used e.g. in
getphraselist() since phrase endings must not include the `.' (which
is legal in phrases).r Nr )rB r? r' rD r) rJ rK )rF rB Zatomlistr r r r^ s zAddrlistClass.getatomc C s g }x| j t| jk r| j| j | jkr8| j d7 _ q| j| j dkrX|j| j q| j| j dkrz| jj| j q| j| j | jkrP q|j| j | j qW |S )zParse a sequence of RFC 2822 phrases.
A phrase is a sequence of words, which are in turn either RFC 2822
atoms or quoted-strings. Phrases are canonicalized by squeezing all
runs of continuous whitespace into one space.
