> *BUG*
> 1. Open settings, change Timezone, save
> 2. Browser reloads. popup hdfs widget chart. Looks like it's using the right 
> timezone
> 3. Close widget, then go and click on background ops. It's not using timezone 
> for when a task is performed.
> 4. Close background ops. popup hdfs widget chart. Now it's back to the old 
> timezone.
> 5. go to settings and you'll see your change is reverted.
> *BUG*
> 1. When saving timezone info, we should not be saving the property based on 
> what is displayed in the UI.
> 2. See attached. This feels really fragile. There has to be some timezone 
> guid that we can persist so that we are not dependent on what is shown to the 
> user. This it important in case we change the display format/info and when we 
> internationalize, we can't get stuck with this.
> *USABILITY*
> 1. On the graph, we should show the timezone we are displaying in. Users will 
> want to know that now since it can change. See slide #1 in attached.
> 2. unrelated to timezone, we should also add Export text next to icon. Also 
> in slide #1.
> 3. Since the Ambari Server timezone matters, we should let the user have this 
> info as well on the settings dialog. See slide #2.
