The Act was intended to save electricity for seven months of the year, during World War I. DST was repealed in 1919 over a Presidential veto, but standard time in time zones remained in law, with the Interstate Commerce Commission (ICC) having the authority over time zone boundaries. Daylight time became a local matter.
