I guess someone forgot to tell T-Mobile about the time change.
 

My Verizon phone has the right time, but T-Mobile is an hour behind.

Anyone else experience this with their carrier?

thats pretty funny :1orglaugh

did you try restarting your phone?

we don't change our time in arizona

My verizon phone is off by an hour!

That was the first thing I did. I found an auto update setting that I changed, although I am not entirely sure how it was able to auto change my time when I travel to different time zones, but missed it at home.

Oh well.

just noticed mine was off.

my t-mobile phone updated ... its probably the tower that didn't update in your area

my t-mobile was perfectly fine... i use my tmobile phones alarm clock every morning... this morning as well and the time was perfectly right...
