The author argues that all clocks are 30 seconds late due to the truncation convention of displaying time without seconds. By comparing the shown time on clocks to the precise time, they illustrate how this leads to an average error of 30 seconds. They propose that rounding to the nearest minute, instead of truncating, would eliminate this error. The author delves into how different cultures approximate time, highlighting the discrepancy between the truncation convention and intuitive rounding at the minute scale. Ultimately, the author challenges the traditional method of displaying time on clocks and questions the validity of the truncation convention.
