This Timezone +4 icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
It consists of two objects, one superimposed on the other. In the background is a semi-folded, generic map that has a zig-zag top and bottom and is covered in small dots. In the foreground is a medium-sized circle with the text "+4" in the middle.
