This Timezone UTC icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,500 icons, all in the same style and quality.
It is an icon for timezone UTC. There is an outline of a folded map that is opened up. The map has nothing but dots inside of it. In the bottom right of the icon, there is the number 0 that covers about a quarter of the map.
