Use correct flags on ACTION_TIME_CHANGED broadcast

When Settings changes the display format for 12/24 hour time, it fakes
an ACTION_TIME_CHANGED broadcast to provoke apps to update their display.
It needs to use the right flags on that broadcast to match the way the
OS sends it when the time actually changes.
