worldcup games in your org-mode agenda

A significant part of the world population will be watching the Football World
Cup in South-Africa this month. For people who use org-mode to organize
their lives, find the schedule of all the games in this message I sent to the
org-mode mailing list.

In order to have the games show up in your agenda, make sure the file is in
your org-agenda-files. If needed, you could add it with something like in
your org-mode settings:

(add-to-list 'org-agenda-files "~/org/fifa-worldcup-2010.org")

One small issue with the schedule is that it use the South-African times, and
there is no automatic way to adjust times for the local time zone. As a
work-around, Juan Pechiar provided the following function which makes it easy
to update all org-timestamps in a file:

(defun uphours (n)
  "update all timestamps n hours"
  (interactive "nAdd hours: ")
  (save-excursion
    (goto-char (point-min))
    (while (re-search-forward "[[<]" nil t)
      (when (org-at-timestamp-p t)
        (org-timestamp-change n 'hour)
        ))))

Evaluate this function (in emacs, put your cursor after the last ")"), then
press C-x C-e. After that, you can go to the file with the world cup
schedule, and give an M-x uphours, provide the offset for your timezone,
compare to South-African time (positive or negative).
