(realname, email_address) and returns the string value suitable
for an RFC 2822 From, To or Cc header.
If the first element of pair is false, then the second element is
returned unmodified.
Optional charset if given is the character set that is used to encode
realname in case realname is not ASCII safe. Can be an instance of str or
a Charset-like object which has a header_encode method. Default is
'utf-8'.

Fri, 09 Nov 2001 01:08:47 -0000
Optional timeval if given is a floating point time value as accepted by
gmtime() and localtime(), otherwise the current time is used.
Optional localtime is a flag that when True, interprets timeval, and
returns a date relative to the local timezone instead of UTC, properly
taking daylight savings time into account.
Optional argument usegmt means that the timezone is written out as
an ascii string, not numeric one (so "GMT" instead of "+0000"). This
is needed for HTTP, and is only used when localtime==False.

If usegmt is True, dt must be an aware datetime with an offset of zero. In
this case 'GMT' will be rendered instead of the normal +0000 required by
RFC2822. This is to support HTTP headers involving date stamps.

Optional idstring if given is a string used to strengthen the
uniqueness of the message id. Optional domain if given provides the
portion of the message id after the '@'. It defaults to the locally
defined hostname.

If called without arguments, return current time. Otherwise *dt*
argument should be a datetime instance, and it is converted to the
local time zone according to the system time zone database. If *dt* is
naive (that is, dt.tzinfo is None), it is assumed to be in local time.
In this case, a positive or zero value for *isdst* causes localtime to
presume initially that summer time (for example, Daylight Saving Time)
is or is not (respectively) in effect for the specified time. A
negative value for *isdst* causes the localtime() function to attempt
to divine whether summer time is in effect for the specified time.
