TimeText
is a layout that shows the current time at the top of the screen.

 
  Use time text to display the time as well as an optional label on the top of the screen. When the device has a round screen time text is curved. When the device has a rectangular screen, time text is straight.
You can add an additional leading content label to the time text. When adding leading content, the full length of the arc should not be larger than a quarter of the watch face.
Anatomy
 
  TimeText with scrollable elements such as
        lists, design the TimeText to fade away when the element
    scrolls. Use Modifier.scrollAway to scroll TimeText vertically in and out of view, based on the scroll state.
