It sets itself using transmissions received from the U.S. government, which include precise timing information from the U.S. Atomic Clock in Colorado. Please note that the radio transmissions that contain the timing information carry best at night. When you first put the batteries in these clocks, they will most likely not receive a strong enough signal to set themselves until the middle of the night.
