Comment 6 for bug 1236288

As a user in the United States, the very first option I looked for in System Settings was for a 24h toggle. I do not like the AM/PM due to space and it is also not what I'm used to. With that said, I am certainly a minority in the US (outside of the military) in using the 24h format. I would love for there to be a toggle for 12/24h format like there is in Android.
