Description:

When Customizing a New Install of Arch, I found that whenever I try to change the clock from 24 hour to Am/PM, the clock doesn't change. In fact, the clock display freezes (as time passes, the time doesn't update). The clock in the settings menu works properly (see attached screenshot). Switching the time back to 24 hour mode unfreezes the clock.


Additional info:
Under the most recent Gnome 3.8.


Steps to reproduce:

1. open up time settings
2. switch clock from 24 hour to AM/PM
3. Notice that while the time in the tiem settings window changes to AM/PM, the clock at top of the screen does not.
4. Notice that the clock at the top of the screen doesn't change it's displayed value as time goes by.
5. Switch the time back to 24 hour mode. Note that thee clock unfreezes.
