I assume you refer to the use of "(STD?)" and "(DST?)". It actually
works since it appears that mktime() will assume GMT if it encounters
something it does not understand, but that is admittedly not a wise
thing to count on, Why icalendar didn't just use "GMT" or "UTC" is not
clear to me.

I can also report that when using emacs version "22.3.1" on Mac OSX 10.5.8,
one also needs to replace the "-1" with "5".
