Only implemented half of arc (from midnight to noon).  

The red circle is current time, make sure it's the top layer.

then there are 6 arc shape goal fields (from bottom to top, you can create them by following sequence).  All follow 6 layers will have (sm.mn0).value() as min value, and (sm.mn1).value() as the max value.

1. sunrise end: light orange for finished color, and white for unfinished color, data field: (sm1.1).value()
2. sunrise start: orange for finished color, and remove color/zero width for unfinished, data field: (sm1).value()
3. blue hour: blue for finished, remove color/zero width for unfinished, data field: (sm1.0).value()
4. dawn: dark blue for finished, remove color/zero width for unfinished
5. nautical dawn: gray for finished, remove color/zero width for unfinished
6. astronomical dawn: dark gray for finish, remove color/zero width for unfinished.
