This post is kind of amusing. While it's good to see Microsoft paying attention to these things, they appear to have completely ignored changes to DST in the neighbouring nation of Iran. The country stopped DST a couple of years ago, but started it up again just a week back, with plenty of official notice having been given last year. And yet is there a patch? No there isn't. The last info MS have on the Iran timezone is that a patch to REMOVE DST (when they stopped two years ago) was NOT included in a rollup LAST YEAR because official word hadn't been received in time. How many years will it be before MS catch up? I hate to say it, but maybe MS would pay more attention if there were US forces in Iran too - till then the needs of the Iranians can presumably be ignored.
