Microsoft's official position on this? According to its own knowledge base, 'Consider any calendar items in the extended DST period to be suspect. I'm also not looking forward to what's going to happen to my calendar when I update the daylight-saving period on my Windows mobile phone. And I'm just waiting my dad, whom I do tech support for, to call me up, utterly bewildered by this change. The same thing happened to my wife's calendar. Since the event was changed everywhere it appeared on my calendar, not just on his 2007 birthday, I had to call my wife to figure out which date was actually correct.Īll my appointments from March 11 to April 1 also moved, including repeating daily appointments that Outlook now wants me to be late for, and even air travel appointments that Outlook wants me to miss entirely. My father-in-law's birth day became a 24-hour event that takes place from 1 a.m. Between March 11 and April 1, all my appointments moved back one hour. When I set up a birthday in Outlook, what makes you think that when the time zone changes, a birthday should move forward or back accordingly? But that's just what happened when I got my automated patch for the new daylight-savings time.
