Leap seconds

The U.S. Naval Observatory has posted a survey to gather information in advance of the International Telecommunications Union Radiocommunications Sector's consideration of a proposal to discontinue the periodic addition of leap seconds to Coordinated Universal Time. Probably of more interest to the maritime professions than the museum crowd, it is worth a look--the more technically minded can find a link there to the .pdf of the Memorandum and white paper from Assistant Secretary of Defense John G. Grimes (from Sept. 3, 2008).

The more general reader may wish to follow the other link at the top of the page to the USNO's leap seconds page. Scientific and historical, this page links to other fascinating resources such as excellent descriptions of different systems of time.
