Or parse-datetime:

It's not much of a bottleneck, no:

(benchmark-elapse (dotimes (i 10000) (parse-time-string "Thu, 04 Jul 2013 20:06:00 +0200")))
=> 1.120856647

But sorting a summary buffer of 5K messages on Date (which some people
do) might get a performance boost.  But I was thinking that it might be
more likely that parse-datetime parses more date strings correctly than
the version in parse-time.el.
