Been told? No, history wrote it:
"When did the US start using daylight savings time?
1918
DST was first implemented in the US with the Standard Time Act of 1918, a wartime measure for seven months during World War I in the interest of adding more daylight hours to conserve energy resources."
here it was implemented 3 years before...in 1915....so you can Blame the British for it..
The idea of adjusting the time throughout the year has been around for centuries. During the height of the Roman Empire, an hour could last 44 minutes in winter and 75 in summer.
However, British builder
William Willett from Chislehurst lobbied for nationwide adoption of daylight savings time in his 1907 pamphlet
The Waste of Daylight. While riding his horse one morning, it is said Willett had a epiphany that "the sun shines upon the land for several hours each day while we are asleep" but there "remains only a brief spell of declining daylight in which to spend the short period of leisure at our disposal."
In other words, Willett's proposal for daylight savings time had one main motivator - for people to enjoy more sunlight. This change was also important for farm workers, for example, who use the extra hour of sunlight to work into the evening during harvest seasons.
Initially, Willett wanted clocks to go forward twenty minutes at 2am on four consecutive Sundays in April, and then to be reversed on four Sundays in September. This was later adjusted to a much simpler idea: a one-hour advancement of clock time in Spring and a one-hour reversal in Autumn.
Willett lobbied for the adoption of DST until his death from influenza in 1915 - just a year before it was adopted as a nationwide policy in the UK in an effort to reduce energy consumption and increase war production during WW1. It was for these same reasons it was adopted in the US in 1918. While this was an emergency law in the UK, it became permanent in 1925 with the passing of the Summer Time Act.
