Automatic Timestamp Update

Automatic Timestamp Update

[David A. Gershman]

I have my "orgmode" structured in multiple files.  However, every time I
save a file I wouldn't mind a "last modified" time stamp to be updated.
 I thought emacs itself had something of this nature but I'm wondering
if anyone has a different idea/method, perhaps orgmode-specific.

Thanks.

Can't help you with something orgmode specific but Emacs does indeed
have something that will do this for you.  Have a look at
"time-stamp".  You can have file specific settings for time-stamp.

For my org files, I have

#+DATE:      2008.12.05 18:43:01

as one of the first lines in the file and then have the following at the end:

---------------------------------------- cut here
* COMMENT Local file settings for Emacs

# Local Variables:
# time-stamp-line-limit: 1000
# time-stamp-format: "%04y.%02m.%02d %02H:%02M:%02S"
# time-stamp-active: t
# time-stamp-start: "#\\+DATE:[ \t]*"
# time-stamp-end: "$"
# End:
---------------------------------------- cut here

Hope this helps.

I should have also added that, besides the bits in the org files, you
need to add the time-stamp command to the write-file-hook list so that
time-stamp is automatically invoked whenever you write the file out:

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

This should be in your .emacs (or equivalent).
