Problem you are trying to solve

I would like to be able to set a custom date format for the timestamp. Right now it uses 24 October 2023 21:17:35 CEST But I would prefer if it was the ISO8601 format 2023-10-24T21:17:35+0200 which is achieved via the format string %FT%T%z

Suggested solution

Under Account Settings -> Sending mail there should be a textbox Date format or Timestamp date format where one can enter a custom format string that will be used instead of the default.

The mentioned location for the setting suggests you want to change the Date header of outgoing messages. That's not possible. The date format used in a the header of an email is defined in the specification for the internet message format.

If that's not what you're asking for, please elaborate on what problem you're trying to solve exactly.

right before the quoted message that one is replying to. I would like to have the option to change the date format in this automatically generated line.

Thanks for clarifying.

We're probably not going to add a setting to allow the user to only change the date format used in the quote header. Instead we'll likely go for a more generic way of customizing the quote header (related: #4449). However, we first need to put in some design work to figure out what the user experience for this should look like.

This doesn't feel like a very high priority item. So it's unlikely we'll get to this anytime soon.
