It depends on whether it’s day or night. If it’s nighttime, use the north star tracking method. The compass will help orient you to the north so you can find the Big Dipper. For telling time in the day, you’ll need to line the compass up with a sun clock, which you can print out online. The way you use it will depend on where you are in the world, since you’ll need to line the clock up with geographic north.
