And if you absolutely insist on doing it this way, make sure you start in the middle of the day -- if your base time is 12:00 noon (which is what I always use in this situation), the furthest it can go because of DST is 11:00 or 13:00, which won't screw you up if all you're interested in is the date.. ;) Cheers!
