How hard is it to add Arizona time to your network

Arizona is on its own Mountain Time Zone without changing for Daylight Savings Time.  This is not a new phenomenon, yet every year you make my phone the wrong time.  I can fix it, but then have to undo that when I travel.

I would think that with all the money you have spent getting the best coverage in Arizona, you would want to invest the small amount to remove this persistent frustration from the customers who are using that coverage.

Is there anything like that in the works, or will we always have to disable it every time we come home, and do all the travelers using Verizon cellular

service have to be an hour early to their first appointment here, or rush madly, thinking they're late?
