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>> 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.
> Henry points out that from a physics perspective, there is only one time.<p>Relativity rather forcefully disagrees with this contention.<p>> The professors—who also propose an unchanging calendar that would always start on a Monday, but let's deal with one crazy time-keeping idea at a time—are hoping that the world will adopt their plan in 2018.<p>It is somewhat more likely that human civilization will be completely annihilated by a to-this-date-unknown object smashing into the Earth between now and 2018 than it is that the world, or any significant subset of the political jurisdiction that exist on it, will adopt this plan in (or by) 2018.
