[source material released on June 20, 1994 by the U.S. Department of Energy] [this file lists unannounced nuclear tests carried out by the United States. The source material was release in a hypertext format on DoE's World Wide Web server, available through URL http://www.doe.gov as part of their openness initiative. For the benefit of those without programs such as Mosaic, I have edited this material into a plain text (ASCII) file. The WWW address listed above is also the place for DoE's OPENNET program to provide a computerized index of declassifed DoE documents. -- Paul McGinnis / TRADER@cup.portal.com / PaulMcG@aol.com Dec. 12, 1994] ----------------------------------------------------------------------------- Expanded Test Information for Nuclear Tests with Unannounced Simultaneous Detonations United States Department of Energy ---------------------------------- (Daylight savings effective 1967) (2AM last Sunday in April through 2AM last Sunday in October) (Year round daylight savings January 6, 1974 through October 26, 1975; however, standard time last Sunday October 1974 through last Sunday February 1975.)
