The Wright brothers ran a bicycle shop in Dayton and did most of their design and wind-tunnel work here, making their first flights at Kitty Hawk because it had the wind and the sand. Their first practical aircraft flew at Huffman Prairie outside the city in 1905.
The clock: Dayton keeps Eastern Time. The 1995 accords that ended the Bosnian war were negotiated at Wright-Patterson Air Force Base here.
Dayton lies at 84.2°W. Its time zone, UTC−5, is built around the 75°W meridian. The 9.2° gap between them means the clock runs roughly 37 minutes ahead of the sun: solar noon arrives at about 12:37 rather than 12:00. Under daylight saving the clocks move 60 minutes forward, widening the gap to 97 minutes and pushing solar noon to 13:37.
