This seems to do what you want:

(setq gnus-summary-line-format "%U%R%z%I%(%[%4L: %-23,23f%]%) %s %~(form 
(format-time-string \"%d-%b-%Y\" (gnus-date-get-time (mail-header-date 
gnus-tmp-header))))@\n")

See (info "(gnus) Advanced Formatting") for the use of `~(form ...)'.
The sexp for the time of the current article I strung together by
looking at the source of `gnus-summary-line-format-alist' and
`gnus-dd-mmm'.

Instead of setq it might be better to use setopt or the Customize UI,
since `gnus-summary-line-format' is a user option.
