NON-RFC-Date-header leads to "01.01.1970 01:00:00"

[ignoreigor]

Hi,
mails sent with FairEmail, an Android-mailing-app, have this date-header set:
Date: Thu, 6 Oct 2022 12:27:13 +0200 (GMT+02:00)
(EML-File offered as attachment)

tine (2022.10.01.62) parses the date and results in "01.01.1970 01:00:00". tine processes date-headers with commented timezones in parenthesis, as long as (GMT) oder (UTC) is given, dates are parsed properly, but additions like (GMT+02:00) avoids date parsing.

Bug or feature - you may decide! Roundcubemail, Outlook or thuderbird are more graceful with resolving that header.

hi Igor,
I'll have a look - thanks for the eml, I'll put this into a phpunit test 👍
