Insert current time in an emacs buffer

A lot of text editors (way back to the days of Borland's SideKick--wow, what a blast!) provided an easy way to insert the current date and time in the file you are editing. This is particularly useful for a notes/journal type of thing.

Emacs (the One True Text Editor) does not provide an "out of the box" way to do this, but a very simple piece of elisp can do it.

I put this (adapted from a suggestion found on the help-gnu-emacs list) in my .emacs:

(defun mr-insert-current-time ()
  (interactive)
  (insert (format-time-string "%F %T")))
(global-set-key (kbd "C-c d") 'mr-insert-current-time)

(defun mr-insert-current-time-block ()
  (interactive)
  (insert "n-------------------n")
  (insert (format-time-string "%F %T"))
  (insert "n-------------------n")
  )
(global-set-key (kbd "C-c C-d") 'mr-insert-current-time-block)

which allows me to press C-c d at any time to get the current date and time in my buffer (formatted the way I like). The second function puts it in a little block, good for seperating entries in a notes log.
