This Timezone -12 icon has Android KitKat style. If you use the icons for Android apps, we recommend using our latest Material Icons icon pack (please check our sidebar on the right). Otherwise, it's a solid icon pack that looks good in small resolutions, either on the web or in print. It's characterized by thick lines, smooth corners, and is optimized for 24x24 pixels.
A timezone -12 icon is represented with a foldout map icon and on the edge of the map there is a circle with a -12 written inside. The map will have straight lines on both sides, but on the top and bottom there will be a zig zag pattern to show it's foldout component.
