The WWVB radio station in Colorado broadcasts the current time on the 60 kHz frequency, taking a full minute to transmit a single digit of binary. Every radio clock in the U.S. uses this station to set its time, offsetting the broadcasted time by the user’s time zone. This innovative solution to timekeeping is a perfect example of American ingenuity, using simple yet effective technology. It serves as a reminder of the countless invisible contributors who have shaped the world we live in today. The station’s continuous broadcasting is a testament to human creativity and problem-solving skills.
