I was just looking to set up an appointment for Monday and noticed that it was showing Mountain and Pacific time as being 2 hours apart. I know that is wrong so I dug into the problem a little bit more thinking I had found a bug in Outlook. It turns out it is just user error. When I added Pacific time as the second time zone I forgot to check the box that tells Outlook to automatically update for daylight savings time. Mountain time was correctly taking into account the change to Daylight savings on Monday but because I hadn't told Outlook to update the Pacific time zone it was still showing standard time. Once I checked the box and closed the dialog they were only 1 hour apart. This once again proves that computers are no smarter than the people running them.
