00:00That's what I found so interesting about this story is that most people won't really notice
00:04if the leap second disappears. I mean, God, I wouldn't notice if we lost a day. But lots of
00:10software will need redesigning and astronomers and Earth scientists and compass navigators,
00:15they'll all need to account for the growing divide. But what I found so fascinating about
00:19this story was some people were genuinely quite kind of melancholy, even heartbroken about the
00:26prospect of severing the link with astronomical time that humans have been using for thousands
00:31of years to tell a day or a year. We're a stargazing species, they say, and humans fundamentally
00:38are animals that live by the sunrise and sunset. So there's a real psychological element to
00:43the story. It's not just a question of science and data and digital infrastructure. It's also
00:48a question of how humans define where we are in a day, in a year.
