org-capture-templates: %date is too long

[Uwe Brauer]

Hi

I try to add a new entry to my org-capture-templates
for mails what I read via gnus. I'd like to have a timestamp that
reflects when the message was received, not when the entry was created
(for that I would to have to use %t)

Now I have set 

         "| | %:fromname|%:fromaddress|%^{Sheet|1|2|3|4|5|6|7|8|9} | %:date |[ 
] | | %a " :prepend t)

Using the description of the org-capture-template

------------------------+------------------------------------------------------
gnus                    |  %:from %:fromname %:fromaddress
                        |  %:to   %:toname   %:toaddress
                        |  %:fromto (either "to NAME" or "from NAME")
                        |  %:date %:date-timestamp (as active timestamp)
                        |  %:date-timestamp-inactive (as inactive timestamp)
gnus                    |  %:group, for messages also all email fields

The problem is this results in 

| Number | name     | email             | sheet | date                          
 | status |
|        | John Doe | footbar@gmail.com |     2 | Tue, 2 Mar 2021 19:35:03 
+0100 | [ ]    |

I don't need the hour, and for sure I don't need +0100

Any idea how to shorten that?
