Over how many degrees of longitude do the imaginary time zones stretch
History of longitude instant in time, local solar time at a location varies by one hour for every 15 degrees change of longitude (360 degrees divided by 24 hours), there is a direct relationship between time and longitude. If the navigator knew the time at a fixed reference point when some event occurred at the ship's location, the difference between the reference time and the apparent local time would give the ship's position relative to the fixed location. Finding apparent local time is relatively easy. The problem, ultimately, was how to determine the time at a distant reference point while on a ship.
Over the Edge Vol. 7: Time Zones Exchange Project from a station called ABS, which closely parodies the Art Bell show. Disc 2 is presented as a "Universal Media Netweb" simulcast, in conjunction with Radio Moscow, to teach the people of Russia the basics of a Free Market economy. Throughout this disc are commercials for Mertz, a Decision-Enhancing Mental Supplement, and a series of recordings from a real botched attempt to do a similar simulcast in the mid 1980s. This album was released in 1994 on Negativland's Seeland label. PART ONE: TIME ZONES EXCHANGE PROJECT 68:47' PART TWO: TESTWAVE 72:10' Over the Edge Vol. 7: Time Zones Exchange Project
