I've been using this zsh function for a year or two:

        jr () {
            echo "---"
            echo "\n##"`date +" %a %D %l:%M%P"` >> ~/journal.txt 
            cat >> ~/journal.txt
        }

It usually emits 72 dashes, so that I can stay within that margin (manually, heh). Edited to not break HN. The '##' is because I habitually markdown format everything.
