Daylight saving time began many years ago when New Zealand entomologist George Hudson wanted extra hours after work to go bug hunting, according to National Geographic. President Woodrow Wilson agreed that daylight saving time was a good idea and in 1918, he signed legislation that would shift the country to the new time system. Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine at Northwestern University in Chicago shares more on the history of daylight saving time and recommendations for how to manage it on In Focus Texas.
