Yes and no, I don't normally use imap but here is what it gives on a
"FETCH ... ALL" command for one of Erwin's mail:
5 FETCH 507 all
* 507 FETCH (FLAGS (\Seen \Recent) 
INTERNALDATE "07-Jun-2018 00:57:18 +0200" 
RFC822.SIZE 2162
ENVELOPE (
 "mar., 05 juin 2018 13:38:20 +0200"
 "[edbrowse-dev] imap"
 (("Erwin" NIL "erwb19" "free.fr"))
 (("Erwin" NIL "erwb19" "free.fr"))
 (("Erwin" NIL "erwb19" "free.fr"))
 ((NIL NIL edbrowse-dev" "lists.the-brannons.com"))
 NIL NIL NIL "<20180505133820.erwb19@free.fr>"
))
5 OK Fetch completed.

So, here again there are two dates:
The "internal date" I was talking about, that is formatted by the server
The "envelope" date that comes from the From litterally.

in mbox format, this is the same as the format you have in the first
line that gives an internal date (date where the mail was dropped in
your mbox) and then the Date: field in the envelope.


So the two things I said still stand:
 - in this case the From ought to be formatted in English according to
the RFC so this is a bug in edbrowse on the send side in the first
place; I would think the first thing to fix is that.
You can check RFC4021 / RFC822 yourself if you do not trust me :)
 - I think in the cases that can still happen where we cannot parse the
date that we are given, it is more reliable to ask the server for the
internaldate (or get it from the file if it is on disk)
I think it makes sense to do like mutt and look at Received because that
is the same in all formats (imap/mbox/mailbox), rather than try to
implement specifics:
7 fetch 507 (BODY[HEADER.FIELDS (RECEIVED)])
* 507 FETCH (BODY[HEADER.FIELDS (RECEIVED)] {994}
Received: by nautica.notk.org (Postfix, from userid 108)
	id 4F67EC01A; Tue,  5 Jun 2018 13:38:28 +0200 (CEST)
...
)
7 OK Fetch completed.


As you can see, it's not the same time, but this only happens for "bad"
clients and it sounds a lot better to me than trying to learn all
possible languages... :D
