It's documented in the "Summary Buffer Lines" node:

@item &user-date;
Age sensitive date format.  Various date format is defined in
@code{gnus-user-date-format-alist}.

There is (currently) no rest to list.

This seems sufficient?

---
All the specs allow for inserting user defined specifiers---@samp{u}.
The next character in the format string should be a letter.  Gnus
will call the function @code{gnus-user-format-function-}@samp{X}, where
@samp{X} is the letter following @samp{%u}.  The function will be passed
a single parameter---what the parameter means depends on what buffer
it's being called from.

So there doesn't seem to be anything here to do, and I'm closing this
bug report.  If you want help with using Gnus, then I suggest asking on
an Emacs help-oriented mailing list.
