Later this month, delegations from around the world will gather in Dubai for a conference to discuss international treaties related to radio frequencies, satellite coordination, and other technical matters. One of the issues they will address is the synchronization of time. Currently, there are two methods of timekeeping – one based on Earth’s rotation and the position of the sun and stars (Universal Time, or UT1), and the other based on atomic clocks and cesium atoms (International Atomic Time, or TAI). Over the years, these two methods have diverged, and leap seconds have been inserted periodically to align them. However, predicting when leap seconds will be necessary has become increasingly difficult and problematic for technology companies and timekeepers around the world. To address this issue, Dr. Judah Levine has proposed a new solution called the “leap minute.” Instead of synchronizing the two clocks every few years, the leap minute would allow atomic time to diverge from astronomical time for a longer period, potentially even 60 seconds. This proposal aims to reduce the frequency of synchronization and provide a more relaxed approach to timekeeping. However, implementing this solution will require consensus among international stakeholders, and it remains to be seen whether it will gain traction at the upcoming conference in Dubai.
