Understanding Earth's Day Length and Its Implications

The video explores how the perception of time has changed, especially since the COVID-19 pandemic, and how the Earth's rotation affects the length of a day. It discusses the shortest day recorded in recent history and how historical data from mollusk fossils show that days were shorter millions of years ago. The Moon's gravitational pull slows Earth's rotation, affecting day length. Technological systems like GPS rely on precise timekeeping, which can be disrupted by these changes. The video also highlights Linode's cloud services for efficient time management.
