After that, sunny skies are in the forecast with a high of 77 on Tuesday and 70 on Wednesday.As for changing our clocks, the twice-a-year occurrence that’s a continual source of conversation, The New York Times has published a story dispelling the myths of the time change.The Times says daylight saving time was not invented by Benjamin Franklin, nor was it an aid to give farmers extra sunlight in the summer.According to The Times, one of the first official proposals to move the clock hands forward came in 1908 when it was unsuccessfully proposed to the British Parliament. It was finally enacted by Germany in 1916 as a cost-savings measure during World War I and adopted three weeks later by the British.The United States first adopted daylight saving time in 1918.
