I want to use C-u M-:, then
(format-time-string "%m/%d/%Y") to insert a customized date string. But it is inserted into the current buffer with double quotes.
Any trick to remove these quotes?

Rather than ask M-: to insert the output of the Elisp code, just write the Elisp code that inserts the text you want:
M-: (insert (format-time-string "%m/%d/%Y")) RET
I think you should not change M-: for this. I have setup C-c + to call the
vicarie/eval-replace-last-sexp defined below. So, I just type
(format-time-string "%Y/%m/%d") and do
(defun vicarie/eval-last-sexp-and-do (f) "Eval the last sexp and call F on its value." (let ((standard-output (current-buffer)) (value (eval-last-sexp nil))) (funcall f value))) (defun vicarie/eval-print-last-sexp () "Evaluate and print the last sexp on the same line." (interactive) (vicarie/eval-last-sexp-and-do (lambda (value) (insert (format " (= %s ) " value))))) (defun vicarie/eval-replace-last-sexp () "Evaluate and replace last sexp with its value." (interactive) (vicarie/eval-last-sexp-and-do (lambda (value) (backward-kill-sexp) (insert (format "%s" value)))))
