This is the Przeszłość icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
The past icon is a represented with a clock. Instead of a complete circle like most clocks are, the clock is shown with an arrow that makes a circle. However, the arrow is going in a counter clockwise motion to show that it is going backwards or in the past.
