Weather Widget Crescent Sun Icon?

On sunny days (no clouds), the weather widget shows a strange solar ecclips icon (sun mostly occluded by dark circle shadow)? Your docs say this is the "Clear Night" icon. But the widget is showing it for the day (not night). I am thinking that the widget can't correctly perform transform from 24 hour clock to 12 hour (AM, PM) system clock settings?

How can this be fixed?
