I type: C-u M-! date RET

A purely emacs lisp alternative would be: 
M-: (insert (current-time-string)) RET


Of course, if you have to do it often, you can do:

(defun insert-timestamp ()
  (interactive)
  (insert (current-time-string)))

(global-set-key (kbd "<f8>") 'insert-timestamp)

so that you only have to type F8 to insert the timestamp.

Here's a couple of versions I use with some formatting and chioce of 
just date or date and time:

(defun insert-date ()
  "Insert current date at point, and newline if point is at beginning of line."
  (interactive)
  (if (prog1 (bolp)
        (let ((time (current-time-string)))
          (insert (substring time 4 11) (substring time 20 24)))
        )
      ;; insert newline if point was at beginning of line
      (insert ?\n))
  )

;; output looks like this:  Feb 25 2010

;; (global-set-key '[(meta f12)] 'insert-date)



(defun insert-date-and-time ()
  "Insert current date and time at point, and newline if point is at 
beginning of line."
  (interactive)
  (if (prog1 (bolp)
        (let ((time (current-time-string)))
          (insert (substring time 4 11) (substring time 20 24) 
(substring time 10 19) ) )
        )
      ;; insert newline if point was at beginning of line
      (insert ?\n))
  )

(global-set-key '[A-home] 'insert-date-and-time)

;; output looks like this:  Feb 25 2010 11:05:43

Have a look at the commentry section of timestamp.el. It shows how this
can be done.

Also, if you need only one time-stamp per file and it's acceptable to
have this time stamp at the top of the buffer, you can put

(add-hook 'write-file-hooks 'time-stamp)

into the .emacs and then the line (or similar)

;; Time-stamp: "2010-02-19 12:15:41 userloginname"

near the top every file you want time-stamped.

The string part is formatted per variable 'time-stamp-format.

Every time the file is saved this commented line will be updated.

I use this function to insert a time stamp at point:

    (defun insert-time-stamp ()
      "Inserts a time stamp 'YYYY-MM-DD HH:MM AM/PM'"
      (interactive)
      (insert (format-time-string "%Y-%m-%d - %I:%M %p")))

I just call that via `M-x insert-time-stamp` unless a higher level
function calls it.  You could call it with a short cut though with
something like

    (global-set-key (kbd "<f12>") 'insert-time-stamp)

if you wanted.

You'll need to evaluate those in your scratch buffer to get them in
the current emacs session.  Paste them in and then `M-x eval-buffer`.

If you want them in all emacs sessions, put them in your .emacs file.
`C-h r m Init File RET`.  Also, [Yegge's .emacs
file](http://steve.yegge.googlepages.com/my-dot-emacs-file) is worth a
read.

Hope that helps.

(defun insert-current-time ()
   "Insert the result of `current-time-string' at point."
   (interactive)
   (insert (current-time-string)))

(global-set-key (kbd "C-c t") 'insert-current-time)

There is a trade-off between simplicity and flexibility, and the solutions on
the wiki favor simplicity over flexibility.  Here's my attempt to support the
user's preference for different date and time formats while still minimizing
keystrokes.

If you post it to the wiki also, then there will be no such distinction. ;-)

Just a suggestion.

Nice gimmick. To make it perfect I'd like insert-time-stamp to replace
region (if there is a region). How to achieve this? (insert "string")
does not replace region but inserts at point.

May be that way:

(defun insert-time-stamp ()
  "Inserts a time stamp 'YYYY-MM-DD HH:MM AM/PM'"
  (interactive "*")
  (let ((beg (when (region-active-p)
               (region-beginning)))
	(end (when
                 (region-active-p) (region-end))))
    (when (and beg end)
      (delete-region beg end)))
  (insert (format-time-string "%Y-%m-%d - %I:%M %p")))

Quite the thing. Many thanks!

Andreas,

this seems gratuitously complicated.  Is there anything wrong with

(defun insert-time-stamp ()
  "Inserts a time stamp 'YYYY-MM-DD HH:MM AM/PM'"
  (interactive "*")
  (when (region-active-p)
      (delete-region (region-beginning) (region-end)))
  (insert (format-time-string "%Y-%m-%d - %I:%M %p")))

Sorta curious, since I am no elisp wizard.

Cheers.
