Note: This page was created way back in 1998 when people actually compiled pages of links manually, which they then had to monitor to make sure none went dead. Can you imagine? While it has been updated periodically since then, there will probably be broken links or things not included that should be. If you find anything amiss or missing, please email me.

Decimalized Time Sites

• The International Meridian Conference Proceedings, Oct. 1884 - Resolution VII of the Final Act of these proceedings, which established the Greenich Prime Meridian, states: "That the Conference expresses the hope that the technical studies designed to regulate and extend the application of the decimal system to the division of angular space and of time shall be resumed, so as to permit he extension of this application to all cases in which it presents real advantages." All parties to the conference voted in the affirmative on this resolution except Germany, Sweden, and Guatemala which abstained.
