when did the us begin using daylight savings time
History of time in the United States Daylight saving time was established by the Standard Time Act of 1918. The Act was intended to save electricity for seven months of the year, during World War I.[3] DST was repealed in 1919 over a Presidential veto,[4] but standard time in time zones remained in law, with the Interstate Commerce Commission (ICC) having the authority over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.
