HARRISBURG – As millions of Pennsylvanians turned their clocks forward last weekend, Lancaster County Sen. Scott Martin is renewing his call to make daylight saving time permanent and eliminate the twice-yearly time changes. Martin introduced Senate Resolution 36 this week urging Congress to make daylight saving time permanent. According to the National Conference of State Legislatures, 13 states have enacted legislation in support of this concept over the last three years. Daylight saving time began as an energy-saving measure in World War I and was made permanent for most states in 1966 with passage of the Uniform Time Act. However, studies show that the twice-a-year time change results in more accidents, health problems and a loss of productivity of more than $400 million annually. Eliminating the transition between standard time and daylight saving time would require action at the federal level.
