In a recent New Yorker article titled "The Thorny Problem of Keeping the Internet’s Time," Judah Levine gives insight into his own work about timekeeping at NIST. According to the article: "Levine has maintained NIST's own N.T.P. service for decades, and he and a select few of his colleagues are responsible for reconciling its master clocks with Universal Coördinated Time, often within billionths of a second. If the companies disliked leap seconds, Levine said, they should have lobbied for change through the intergovernmental bodies that have the power to abolish them. (Levine himself would prefer a world without leap seconds, and the U.S. government, with his help, has proposed eliminating them for the sake of computer systems; astronomers and other governments have objected. The next opportunity for formal discussion will come in 2023, and the matter is already actively being debated.) "
