He suggested that standard time zones could be used locally, but they were subordinate to his single world time, which he called Cosmic Time.<p>Thus, we can look again at the argument from the article:<p>&gt; If 19th-century technology brought the world closer together, then Hanke and Henry argue that the Internet has eliminated distance completely<p>and realize that a single clock was also a proposed solution to 19th-century problems, and the internet (or long-distance telephone service) is not a key difference between now and the previous 150 years.
