Anyone else live in AZ?

[vMAC]

I'm seeming to have a problem and I'm hoping it's just something that I'm doing wrong with the phone. I live in Arizona so there is no DST time zone change when the season changes. Right now when I'm in Arizona it works fine I don't have any problems; but I travel frequently to other states particularly Seattle, Washington; Dayton, OH; and Atlanta, GA. Whenever I travel to any of those places not only is the time wrong on my phone (which I have set to get the time from the network and I'm on Sprint) but it also throws off the timing of my appointments. It's really baffling when I travel to Seattle; which is currently on the same time as I am it shows the time as being an hour later than it really is, and it shows my appointments to be an hour later than they really are? Anyone else having this problem? Anyone know of a quick way that I can fix this?
