This Timezone +5 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 a combination of two overlayed objects. The background object is a generic map-like object that has zig-zag top and bottom edges and dots scattered on it. The foreground object is a circle in the lower-right of the map that has a large "+5" text in it.
